X2Y Series Surface-mount Ceramic EMI Filter Capacitors

The X2Y series represents a breakthrough in integrated passive device (IPD) technology, offering a unique 4-terminal ceramic multilayer component for decoupling and filtering. Integrating two Y-capacitors and one X-capacitor into standard MLCC sizes, the X2Y device leverages its multilayer construction for internal noise cancellation, significantly reducing Equivalent Series Inductance (ESL) from nanohenry to picohenry levels. This balanced design provides superior broadband filtering and decoupling capabilities, enabling better EMC compliance across a wide range of applications.

Key Features and Benefits

• Fewer Components: One X2Y can replace multiple inductors and/or capacitors, and up to 1:7 MLCCs in power delivery bypass networks.
• Superior Performance: Eliminates both differential and common mode noises with ultra-low ESL.
• Cost Savings: Reduces assembly costs through lower component count and placement.
• Board Level Advantages: Minimizes via drills, improving routing flexibility.
• Broadband Effectiveness: Operates effectively up to 10 GHz and beyond.
• Bypass Capability: Operates in bypass mode without DC current limitations, unlike feedthrough capacitors.
• Matched Y-caps: Features two tightly matched line-to-ground capacitors with superior balance in temperature and voltage variations, and equal aging effects.
