Ceramic X2Y® EMI Filter Capacitors

Pulse Electronics, a YAGEO Company, offers the X2Y series EMI filter capacitors which are a breakthrough in the design of ceramic multilayer products for decoupling and filtering in an integrated passive device (IPD). X2Y products integrate two Y-capacitors and one X-capacitor into a 4-terminal device which is available in standard MLCC sizes. Unique multilayer construction provides noise cancellation within the device, reducing ESL from nanohenry to picohenry levels. Using the unique balance between the Y-capacitors and the shielded multilayer structure, the X2Y products offer superior decoupling and filtering. The X2Y device performs as a broadband filter enabling better EMC compliance for electrical equipment in a wide range of applications.

Features

• Broadband filtering and decoupling: X2Y is effective up to 10 GHz and frequencies beyond
• Ultra-low ESL: noise cancellation within X2Y reduces ESL from nanohenry to picohenry levels
• Bypass: unlike feed-through capacitors, X2Y is in bypass, so there are no DC limitations
• Matched Y-caps: two tightly matched line-to-ground capacitors in one device
• Superior balance: temperature and voltage variations balanced between two Y-caps
• Aging reliability: aging effects are equal on two Y-caps

Benefits

• Fewer components in filtering: one X2Y can replace multiple inductors and/or capacitors
• Superior performance in filtering: one X2Y can eliminate both differential and common-mode noises
• Fewer components in decoupling: up to 1:7 replacement of MLCCs in power delivery system bypass networks
• Superior performance in decoupling: large or small, X2Y components exhibit ultra-low ESL
• Total cost savings: assembly cost savings through reduced component count and placement costs
• Board level design advantages: dramatically reduces via drills, which blocks routing
