Surface-mount ceramic
EMI filter capacitors
X2Y® Series
DESCRIPTION
X2Y® series is a breakthrough in the design of ceramic multilayer products for decoupling and filtering in an IPD
(integrated passive device).
X2Y® products comprise two Y-capacitors and one X-capacitor, integrated into a 4 terminal device, which is available
in standard MLCC sizes. Thanks to the unique multilayer construction the device 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
BENEFITS
•
Fewer Component in Filtering: One X2Y® can
replace multiple inductors and/or capacitors
•
Broadband Filtering and Decoupling: X2Y® is
effective up to 10 GHz and frequencies beyond
• Ultra Low ESL: Noise cancellation within X2Y®
makes ESL reducing from nanohenry to
picohenry levels
•
Superior Performance in Filtering: One X2Y®
can eliminate both differential and common mode
noises
•
•
•
•
Bypass: Unlike feedthrough capacitors, X2Y® is
in bypass, so no DC current limitations
•
Fewer Component in Decoupling: Up to 1:7
replacement of MLCC in power delivering system
bypass networks
Matched Y-caps: Two tightly matched line to
ground capacitors in one device
•
•
Superior Performance in Decoupling: Large or
small, X2Y® components exhibit ultra low ESL
Superior Balance: Temperature and voltage
variations balanced of two Y-caps
Total Cost Savings: Assembly cost savings
through reduced component count and placement
costs
Aging Reliability: Aging effects are equal on
two Y-caps
•
Board Level Design Advantages: Dramatically
reduces via drills, which blocks routing
