LoRho Surface Mount Series RoHS
Littelfuse LoRho Surface Mount PPTC (Polymer Positive
Temperature Coefficient) devices provide overcurrent
protection for applications where ultra low internal
resistance, ultra low voltage drop and automatic
resettable protection are desired. This new series allows
a higher hold current device in a smaller factor and lower
profile as compared to a standard PPTC. It offers ultra
low internal resistance while maintaining the high level
electrical characteristics and performances of standard
PPTC products. All devices are UL recognized and TUV
approved and have maximum fault current of 50A. They
are available in 0402 to 2920 sizes while the hold current
ranges from 100mA to 7A.
Littelfuse 0402 size LoRho SMD PPTC is the smallest
size surface mounted PPTC device available in the
market.

WARNING
• Users shall independently assess the suitability of these devices for each of their applications
• Operation of these devices beyond the stated maximum ratings could result in damage to the devices and lead to electrical arcing and/or fire
These devices are intended to protect against the effects of temporary over-current or over-temperature conditions and are not intended to perform as protective devices where such
conditions are expected to be repetitive or prolonged in duration
• Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can adversely affect the performance of these PPTC devices
These devices undergo thermal expansion under fault conditions, and thus shall be provided with adequate space and be protected against mechanical stresses
• Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the PPTC device.

I hold = Hold current: maximum current device will pass without tripping in 20°C still air.
I trip = Trip current: minimum current at which the device will trip in 20°C still air.
V max = Maximum voltage device can withstand without damage at rated current (I max)
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax)
P d = Power dissipated from device when in the tripped state at 20°C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow
soldering of 260°C for 20 sec.
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
Notes:
0805L150SL and 1206L150SL are ideal for overcurrent protection in VBUS of USB 3.0 / USB 2.0 ports.
* 1206L380SLTH has Ihold 2.82A for at least 15min @ 55ºC. It is ideal for overcurrent protection in Li-ion / Li-Polymer battery packs of smartphones.
** 1812L350SL Typical Time-To-Trip is 50A at 0.013-0.020 seconds. R1min=0.015ohm (resistance range 0.015-0.025ohm).
*** 2920L700SL is ideal for overcurrent protection in Li-ion / Li-Polymer battery packs of tablet PC.
