Product Overview
The X2Y Series Surface-mount ceramic EMI filter capacitors are integrated passive devices (IPD) designed for decoupling and filtering applications. These components integrate two Y-capacitors and one X-capacitor into a single 4-terminal device, available in standard MLCC sizes. Their unique multilayer construction enables noise cancellation, significantly reducing Equivalent Series Inductance (ESL) from nanohenry to picohenry levels. This design offers superior broadband filtering and decoupling performance, enabling better EMC compliance for electrical equipment.
