Product Overview

The X2Y Series Surface-mount ceramic EMI filter capacitors are integrated passive devices designed for decoupling and filtering. They combine two Y-capacitors and one X-capacitor into a single 4-terminal component, available in standard MLCC sizes. This unique multilayer construction enables noise cancellation, significantly reducing Equivalent Series Inductance (ESL) from nanohenry to picohenry levels, offering superior broadband filtering and decoupling performance.

Technical Specifications

Advantages & Applications

Advantages

• Fewer Components in Filtering: One X2Y can replace multiple inductors and/or capacitors.
• Superior Performance in Filtering: Eliminates both differential and common mode noises.
• Fewer Components in Decoupling: Up to 1:7 replacement of MLCCs in power delivering system bypass networks.
• Superior Performance in Decoupling: Exhibits ultra low ESL.
• Total Cost Savings: Reduces assembly cost through decreased component count and placement.
• Board Level Design Advantages: Dramatically reduces via drills, which aids routing.
• Broadband Filtering and Decoupling: Effective up to 10 GHz and beyond.
• Ultra Low ESL: Noise cancellation reduces ESL from nanohenry to picohenry levels.
• Bypass: No DC current limitations as it operates in bypass mode.
• Matched Y-caps: Two tightly matched line-to-ground capacitors in one device.
• Superior Balance: Temperature and voltage variations are balanced for the two Y-caps.
• Aging Reliability: Aging effects are equal on both Y-caps.
