  for the prevention of defects which might directly cause damage to the third party's life, body or property.
   ①Aircraft equipment Aerospace equipment Undersea equipment Power plant control equipment
   ⑤Medical equipment Transportation equipment(vehicles,trains,ships,etc.) Traffic signal equipment
   ⑧Disaster prevention / crime prevention equipment Data-processing equipment
   ⑩Application of similar complexity and/or reliability requirements to the applications listed in the above.
Storage and Operation condition
1. The performance of chip multilayer ceramic capacitors may be affected by the storage conditions.
1-1. Store the capacitors in the following conditions:
Room Temperature of +5 to +40 and a Relative Humidity of 20% to 70%.
(1) High temperature and humidity conditions may accelerate the deterioration of solderability due to oxidation
 
of the terminal electrodes and deterioration of taping/packaging performance.
Therefore, maintain the appropriate storage temperature and humidity.
(2) Prolonged storage may cause oxidation of the electrodes and deterioration of the packaging materials.
If more than six months have elapsed since delivery, check the mounting before use.
If more than one year has elapsed since delivery, also check the solderability before use.
Even if the storage period is short, do not exceed the specified atmospheric conditions.
(3) Store the capacitors in the original packaging without opening the smallest packing unit.
Do not exceed the above atmospheric conditions for any length of time.
1-2. Corrosive gas can react with the termination (external) electrodes or lead wires of capacitors, and result
in poor solderability. Do not store the capacitors in an atmosphere consisting of corrosive gas (e.g.,hydrogen
sulfide, sulfur dioxide, chlorine, ammonia gas etc.).
1-3. Due to moisture condensation caused by rapid humidity changes, or the photochemical change caused
by direct sunlight on the terminal electrodes and/or the resin/epoxy coatings, the solderability and
electrical performance may deteriorate. Do not store capacitors under direct sunlight or in high huimidity
conditions

1.Temperature Dependent Characteristics
1. The electrical characteristics of the capacitor can change with temperature.
1-1. For capacitors having larger temperature dependency, the capacitance may change with temperature
changes. The following actions are recommended in order to ensure suitable capacitance values.
(1) Select a suitable capacitance for the operating temperature range.
(2) The capacitance may change within the rated temperature.
When you use a high dielectric constant type capacitor in a circuit that needs a tight (narrow) capacitance
tolerance (e.g., a time-constant circuit), please carefully consider the temperature characteristics, and
carefully confirm the various characteristics in actual use conditions and the actual system.

2.Measurement of Capacitance
1. Measure capacitance with the voltage and frequency specified in the product specifications.
1-1. The output voltage of the measuring equipment may decrease occasionally when capacitance is high.
Please confirm whether a prescribed measured voltage is impressed to the capacitor.
1-2. The capacitance values of high dielectric constant type capacitors change depending on the AC voltage applied.
Please consider the AC voltage characteristics when selecting a capacitor to be used in a AC circuit.
3.Applied Voltage
1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications.
1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage.
(1) When AC voltage is superimposed on DC voltage, the zero-to-peak voltage shall not exceed the rated DC voltage.
When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage.
(2) Abnormal voltages (surge voltage, static electricity, pulse voltage, etc.) shall not exceed the rated DC voltage.
Typical Voltage Applied to the DC capacitor
DC Voltage DC Voltage+AC AC Voltage Pulse Voltage
(EMaximum possible applied voltage.)
1-2. Influence of over voltage
Over voltage that is applied to the capacitor may result in an electrical short circuit caused by the breakdown
of the internal dielectric layers .
The time duration until breakdown depends on the applied voltage and the ambient temperature.
4.Type of Applied Voltage and Self-heating Temperature
1.Confirm the operating conditions to make sure that no large current is flowing into the capacitor due to the
continuous application of an AC voltage or pulse voltage.
When a DC rated voltage product is used in an AC voltage circuit or a pulse voltage circuit, the AC current
or pulse current will flow into the capacitor; therefore check the self-heating condition.
Please confirm the surface temperature of the capacitor so that the temperature remains within the upper limits
of the operating temperature, including the rise in temperature due to self-heating. When the capacitor is
used with a high-frequency voltage or pulse voltage, heat may be generated by dielectric loss.
<Applicable to Rated Voltage of less than 100VDC>
The load should be contained so that the self-heating
 of the capacitor body remains below 20°C ,
 when measuring at an ambient temperature of 25°C.

5. DC Voltage and AC Voltage Characteristic
1. The capacitance value of a high dielectric constant type
capacitor changes depending on the DC voltage applied.
Please consider the DC voltage characteristics when a
capacitor is selected for use in a DC circuit.
1-1. The capacitance of ceramic capacitors may change
sharply depending on the applied voltage. (See figure)
Please confirm the following in order to secure the
capacitance.
(1) Determine whether the capacitance change caused
by the applied voltage is within the allowed range .
(2) In the DC voltage characteristics, the rate of
capacitance change becomes larger as voltage
increases, even if the applied voltage is below
the rated voltage. When a high dielectric constant
type capacitor is used in a circuit that requires a
tight (narrow) capacitance tolerance (e.g., a time
constant circuit), please carefully consider the
voltage characteristics, and confirm the various
characteristics in the actual operating conditions
  of the system.
2. The capacitance values of high dielectric
constant type capacitors changes depending
on the AC voltage applied.
Please consider the AC voltage characteristics
when selecting a capacitor to be used in a
AC circuit.
6. Capacitance Aging
[ Example of Change Over Time (Aging characteristics) ]
1. The high dielectric constant type capacitors
have an Aging characteristic in which the capacitance
value decreases with the passage of time.
When you use a high dielectric constant type
capacitors in a circuit that needs a tight (narrow)
capacitance tolerance (e.g., a time-constant circuit),
please carefully consider the characteristics
of these capacitors, such as their aging, voltage,
and temperature characteristics. In addition,
check capacitors using your actual appliances
at the intended environment and operating conditions.
7.Vibration and Shock
1. Please confirm the kind of vibration and/or shock, its condition, and any generation of resonance.
Please mount the capacitor so as not to generate resonance, and do not allow any impact on the terminals.
2. Mechanical shock due to being dropped may cause damage or
a crack in the dielectric material of the capacitor.
Do not use a dropped capacitor because the quality and reliability
may be deteriorated.
3. When printed circuit boards are piled up or handled, the corner
 of another printed circuit board
should not be allowed to hit the capacitor in order to avoid
a crack or other damage to the capacitor.

1.Mounting Position
1. Confirm the best mounting position and direction that minimizes the stress imposed on the capacitor during flexing
or bending the printed circuit board.
1-1.Choose a mounting position that minimizes the stress imposed on the chip during flexing or bending of the board.
  [Component Direction]
Locate chip horizontal to the
direction in which stress acts.
(Bad Example) (Good Example)
[Chip Mounting Close to Board Separation Point]
It is effective to implement the following measures, to reduce stress in separating the board.
It is best to implement all of the following three measures; however, implement as many measures as possible
to reduce stress.
Stress Level
(1) Turn the mounting direction of the component parallel to the board separation surface.
A > D *1
(2) Add slits in the board separation part.
A > B
(3) Keep the mounting position of the component away from the board separation surface.
A > C
*1 A > D is valid when stress is added vertically to the perforation as with Hand Separation.
If a Cutting Disc is used, stress will be diagonal to the PCB, therefore A > D is invalid.
[Mounting Capacitors Near Screw Holes]
When a capacitor is mounted near a screw hole, it may be affected by the board deflection that occurs during
the tightening of the screw. Mount the capacitor in a position as far away from the screw holes as possible.
 
2.Information before Mounting
1. Do not re-use capacitors that were removed from the equipment.
2. Confirm capacitance characteristics under actual applied voltage.
3. Confirm the mechanical stress under actual process and equipment use.
4. Confirm the rated capacitance, rated voltage and other electrical characteristics before assembly.
5. Prior to use, confirm the solderability of capacitors that were in long-term storage.
6. Prior to measuring capacitance, carry out a heat treatment for capacitors that were in long-term storage.
7.The use of Sn-Zn based solder will deteriorate the reliability of the MLCC.
Please contact our sales representative or product engineers on the use of Sn-Zn based solder in advance.

3.Maintenance of the Mounting (pick and place) Machine
1. Make sure that the following excessive forces are not applied to the capacitors.
Check the mounting in the actual device under actual use conditions ahead of time.
1-1. In mounting the capacitors on the printed circuit board, any bending force against them shall be kept
to a minimum to prevent them from any damage or cracking. Please take into account the following precautions
and recommendations for use in your process.
(1) Adjust the lowest position of the pickup nozzle so as not to bend the printed circuit board.
  [Incorrect]
  [Correct]
2.Dirt particles and dust accumulated in the suction nozzle and suction mechanism prevent the nozzle from
moving smoothly. This creates excessive force on the capacitor during mounting, causing cracked chips.
Also, the locating claw, when worn out, imposes uneven forces on the chip when positioning, causing cracked chips.
The suction nozzle and the locating claw must be maintained, checked and replaced periodically.

This makes the chip more susceptible to mechanical and thermal stress on the board and may cause the chips to crack.
4-2. Too little solder paste results in a lack of adhesive strength on the termination, which may result in chips breaking loose
from the PCB.
4-3. Please confirm that solder has been applied smoothly to the termination.
Make sure not to impose any abnormal mechanical shocks to the PCB.

4-3.Correction of Soldered Portion
When sudden heat is applied to the capacitor, distortion caused by the large temperature difference occurs internally,
and can be the cause of cracks. Capacitors also tend to be affected by mechanical and thermal stress depending
on the board preheating temperature or the soldering fillet shape, and can be the cause of cracks.
Please refer to "1. PCB Design" or "3. Optimum solder amount" for the solder amount and the fillet shapes.
1. Correction with a Soldering Iron
1-1. In order to reduce damage to the capacitor, be sure to preheat the capacitor and the mounting board.
Preheat to the temperature range shown in Table 3. A hot plate, hot air type preheater, etc. can be used for preheating.
1-2. After soldering, do not allow the component/PCB to cool down rapidly.
1-3. Perform the corrections with a soldering iron as quickly as possible. If the soldering iron is applied too long,
there is a possibility of causing solder leaching on the terminal electrodes, which will cause deterioration of the
adhesive strength and other problems.

2. Correction with Spot Heater
Compared to local heating with a soldering iron, hot air heating by a spot heater heats the overall component
and board, therefore, it tends to lessen the thermal shock. In the case of a high density mounted board,
a spot heater can also prevent concerns of the soldering iron making direct contact with the component.
2-1. If the distance from the hot air outlet of the spot heater to the component is too close, cracks may occur due to
thermal shock. To prevent this problem, follow the conditions shown in Table 4.
2-2. In order to create an appropriate solder fillet shape, it is recommended that hot air be applied at the angle shown
in Figure 1.

Application Time Less than 10 seconds
3. Optimum solder amount when re-working with a soldering iron
3-1. If the solder amount is excessive, the risk of cracking is higher
    during board bending or any other stressful condition.
Too little solder amount results in a lack of adhesive strength
on the termination, which may result in chips breaking
loose from the PCB.
Please confirm that solder has been applied smoothly is in section
and rising to the end surface of the chip.
3-2. A soldering iron with a tip of ø3mm or smaller should be used.
It is also necessary to keep the soldering iron from touching
the components during the re-work.
3-3. Solder wire with ø0.5mm or smaller is required for soldering.

5.Washing
Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips
or broken solder joints. Before starting your production process, test your cleaning equipment / process to insure
it does not degrade the capacitors.
6.Electrical Test on Printed Circuit Board
1. Confirm position of the support pin or specific jig, when inspecting the electrical performance of a
capacitor after mounting on the printed circuit board.
1-1. Avoid bending the printed circuit board by the pressure of a test-probe, etc.
The thrusting force of the test probe can flex the PCB, resulting in cracked chips or open solder
joints. Provide support pins on the back side of the PCB to prevent warping or flexing.
Install support pins as close to the test-probe as possible.
1-2. Avoid vibration of the board by shock when a test -probe contacts a printed circuit board.
[Not Recommended] [Recommended]
7.Printed Circuit Board Cropping
1. After mounting a capacitor on a printed circuit board, do not apply any stress to the capacitor that
caused bending or twisting the board.
1-1. In cropping the board, the stress as shown may cause the capacitor to crack.
Cracked capacitors may cause deterioration of the insulation resistance, and result in a short.
Avoid this type of stress to a capacitor.
[Bending] [Twisting]
2. Check the cropping method for the printed circuit board in advance.
2-1. Printed circuit board cropping shall be carried out by using a jig or an apparatus (Disc separator, router
type separator, etc.) to prevent the mechanical stress that can occur to the board.
* When a board separation jig or disc separator is used, if the following precautions are not observed,
a large board deflection stress will occur and the capacitors may crack.
Use router type separator if at all possible.

(1) Example of a suitable jig
[In the case of Single-side Mounting]
An outline of the board separation jig is shown as follows.
Recommended example: Stress on the component mounting position can be minimized by holding the
portion close to the jig, and bend in the direction towards the side where the capacitors are mounted.
Not recommended example: The risk of cracks occurring in the capacitors increases due to large stress
being applied to the component mounting position, if the portion away from the jig is held and bent in the
direction opposite the side where the capacitors are mounted.
[Outline of jig] [Hand Separation]
[In the case of Double-sided Mounting]
Since components are mounted on both sides of the board, the risk of cracks occurring can not be avoided with the
above method. Therefore, implement the following measures to prevent stress from being applied to the components.
  (Measures)
(1) Consider introducing a router type separator.
   If it is difficult to introduce a router type separator, implement the following measures.
(Refer to item 1. Mounting Position)
(2) Mount the components parallel to the board separation surface.
(3) When mounting components near the board separation point, add slits in the separation position
near the component.
(4) Keep the mounting position of the components away from the board separation point.
(2) Example of a Disc Separator
An outline of a disc separator is shown as follows. As shown in the Principle of Operation, the top
blade and bottom blade are aligned with the V-grooves on the printed circuit board to separate the board.
In the following case, board deflection stress will be applied and cause cracks in the capacitors.
(1) When the adjustment of the top and bottom blades are misaligned, such as deviating in the top-bottom,
left-right or front-rear directions
(2) The angle of the V groove is too low, depth of the V groove is too shallow, or the V groove is misaligned
top-bottom
IF V groove is too deep, it is possible to brake when you handle and carry it. Carefully design depth of the
V groove with consideration about strength of material of the printed circuit board.

(3) Example of Router Type Separator
The router type separator performs cutting by a router
rotating at a high speed. Since the board does not
bend in the cutting process, stress on the board can
be suppressed during board separation.
When attaching or removing boards to/from the router type
separator, carefully handle the boards to prevent bending.
8. Assembly
1. Handling
If a board mounted with capacitors is held with one hand, the board may bend.
Firmly hold the edges of the board with both hands when handling.
If a board mounted with capacitors is dropped, cracks may occur in the capacitors.
Do not use dropped boards, as there is a possibility that the quality of the capacitors may be impaired.
2. Attachment of Other Components
2-1. Mounting of Other Components
Pay attention to the following items, when mounting other components on the back side of the board after
capacitors have been mounted on the opposite side.
When the bottom dead point of the suction nozzle is set too low, board deflection stress may be applied
to the capacitors on the back side (bottom side), and cracks may occur in the capacitors.
· After the board is straightened, set the bottom dead point of the nozzle on the upper surface of the board.
· Periodically check and adjust the bottom dead point.
2-2. Inserting Components with Leads into Boards
When inserting components (transformers, IC, etc.) into boards, bending the board may cause cracks in the
capacitors or cracks in the solder. Pay attention to the following.
· Increase the size of the holes to insert the leads, to reduce the stress on the board during insertion.
· Fix the board with support pins or a dedicated jig before insertion.
· Support below the board so that the board does not bend. When using support pins on the board,
periodically confirm that there is no difference in the height of each support pin.
2-3. Attaching/Removing Sockets and/or connectors
The board may bend when a socket and/or connector are attached or removed.
Plan the work so that the board does not bend when a socket and/or connector are attached or removed.
2-4. Tightening Screws
The board may be bent, when tightening screws, etc. during the attachment of the board to a shield or
chassis. Pay attention to the following items before performing the work.
· Plan the work to prevent the board from bending.
· Use a torque screwdriver, to prevent over-tightening of the screws.
· The board may bend after mounting by reflow soldering, etc. Please note, as stress may be applied
to the chips by forcibly flattening the board when tightening the screws.

1. Notice for Pattern Forms
1-1. Unlike leaded components, chip components are susceptible to flexing stresses since they are mounted
directly on the substrate.
They are also more sensitive to mechanical and thermal stresses than leaded components.
Excess solder fillet height can multiply these stresses and cause chip cracking.
When designing substrates, take land patterns and dimensions into consideration to eliminate the possibility
of excess solder fillet height.
1-2. There is a possibility of chip cracking caused by PCB expansion/contraction with heat, because stress
on a chip is different depending on PCB material and structure.When the thermal expansion coefficient
greatly differs between the board used for mounting and the chip,it will cause cracking of the chip due to
the thermal expansion and contraction. When capacitors are mounted on a fluorine resin printed circuit
board or on a single-layered glass epoxy board, it may also cause cracking of the chip for the same reason.

3. Board Design
When designing the board, keep in mind that
the amount of strain which occurs will increase
  depending on the sizeand material of the board.
2.Item to be confirmed for Flow sordering
  If you want to temporarily attach the capacitor
  to the board using an adhesive agent before
  soldering the capacitor, first be sure that the
  conditions are appropriate for affixing the
  capacitor. If the dimensions of the land, the type of adhesive,the amount of coating, the contact surface area,
  the curing temperature, or other conditions are inappropriate, the characteristics of the capacitor may deteriorate.
1. Selection of Adhesive
1-1. Depending on the type of adhesive, there may be a decrease in insulation resistance. In addition, there is a chance
that the capacitor might crack from contractile stress due to the difference in the contraction rate of the capacitor
and the adhesive.
1-2. If there is not enough adhesive, the contact surface area is too small, or the curing temperature or curing time
are inadequate, the adhesive strength will be insufficient and the capacitor may loosen or become disconnected
during transportation or soldering. If there is too much adhesive, for example if it overflows onto the land, the result
could be soldering defects, loss of electrical connection, insufficient curing, or slippage after the capacitor is mounted.
Furthermore, if the curing temperature is too high or the curing time is too long, not only will the adhesive strength
be reduced, but solderability may also suffer due to the effects of oxidation on the terminations (outer electrodes)
of the capacitor and the land surface on the board.
 (1) Selection of Adhesive
 Epoxy resins are a typical class of adhesive. To select the proper adhesive, consider the following points.
 1) There must be enough adhesive strength to prevent the component from loosening or slipping during the
    mounting process.
 2) The adhesive strength must not decrease when exposed to moisture during soldering.
  3) The adhesive must have good coatability and shape retention properties.
  4) The adhesive must have a long pot life.
 5) The curing time must be short.
  6) The adhesive must not be corrosive to the exterior of the capacitor or the board.
  7) The adhesive must have good insulation properties.
  8) The adhesive must not emit toxic gases or otherwise be harmful to health.
  9) The adhesive must be free of halogenated compounds.
 (2) Use the following illustration as a guide to the amount of adhesive to apply.

2.Flux
2-1. An excessive amount of flux generates a large quantity of flux gas, which can cause a deterioration of solderability,
  so apply flux thinly and evenly throughout. (A foaming system is generally used for flow solderring.)
2-2. Flux containing too high a percentage of halide may cause corrosion of the terminations unless there is
  sufficient cleaning. Use flux with a halide content of 0.1% max.
2-3. Do not use strong acidic flux.
2-4. Do not use water-soluble flux.*
  (*Water-soluble flux can be defined as non-rosin type flux including wash-type flux and non-wash-type flux.)
3.Leaching of the terminations
Set temperature and time to ensure that leaching of the
terminations does not exceed 25% of the chip end
area as a single chip (full length of the edge A-B-C-D
shown at right) and 25% of the length A-B shown as
mounted on substrate.

Do not use water-soluble flux.*
(*Water-soluble flux can be defined as non-rosin type flux including wash-type flux and non-wash-type flux.)
4.Washing
1. Please evaluate the capacitor using actual cleaning equipment and conditions to confirm the quality,
and select the solvent for cleaning.
2. Unsuitable cleaning solvent may leave residual flux or other foreign substances, causing deterioration of
electrical characteristics and the reliability of the capacitors.
3. Select the proper cleaning conditions.
3-1. Improper cleaning conditions (excessive or insufficient) may result in the deterioration of the performance
of the capacitors.
5.Coating
1. A crack may be caused in the capacitor due to the stress of the thermal contraction of the resin during curing process.
The stress is affected by the amount of resin and curing contraction. Select a resin with low curing contraction.
The difference in the thermal expansion coefficient between a coating resin or a molding resin and the capacitor
may cause the destruction and deterioration of the capacitor such as a crack or peeling, and lead to the deterioration
of insulation resistance or dielectric breakdown.
Select a resin for which the thermal expansion coefficient is as close to that of the capacitor as possible.
A silicone resin can be used as an under-coating to buffer against the stress.
2. Select a resin that is less hygroscopic.
Using hygroscopic resins under high humidity conditions may cause the deterioration of the insulation resistance
of a capacitor. An epoxy resin can be used as a less hygroscopic resin.
3The halogen system substance and organic acid are included in coating material, and a chip corrodes
  by the kind of Coating material. Do not use strong acid type.

1.Transportation
1. The performance of a capacitor may be affected by the conditions during transportation.
1-1. The capacitors shall be protected against excessive temperature, humidity and mechanical force during transportation.
(1) Climatic condition
 ・ low air temperature : -40
change of temperature air/air : -25/+25
low air pressure : 30 kPa
change of air pressure : 6 kPa/min.
(2) Mechanical condition
Transportation shall be done in such a way that the boxes are not deformed and forces are not directly passed
on to the inner packaging.
1-2. Do not apply excessive vibration, shock, or pressure to the capacitor.
(1) When excessive mechanical shock or pressure is applied to a capacitor, chipping or cracking may occur
in the ceramic body of the capacitor.
(2) When the sharp edge of an air driver, a soldering iron, tweezers, a chassis, etc. impacts strongly on the surface
of the capacitor, the capacitor may crack and short-circuit.
1-3. Do not use a capacitor to which excessive shock was applied by dropping etc.
A capacitor dropped accidentally during processing may be damaged.
2.Characteristics Evaluation in the Actual System
1. Evaluate the capacitor in the actual system,to confirm that there is no problem with the performance and specification
values in a finished product before using.
2. Since a voltage dependency and temperature dependency exists in the capacitance of high dielectric type ceramic
capacitors, the capacitance may change depending on the operating conditions in the actual system.
Therefore,be sure to evaluate the various characteristics, such as the leakage current and noise absorptivity,
which will affect the capacitance value of the capacitor.
3. In addition,voltages exceeding the predetermined surge may be applied to the capacitor by the inductance in
the actual system. Evaluate the surge resistance in the actual system as required.
