Surface-mount ceramic
EMI filter capacitors
DESCRIPTION
X2Y
®
Series
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 identical 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
•
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
•
Bypass:
Unlike feedthrough capacitors,
bypass, so no DC current limitations
X2Y
®
is in
BENEFITS
•
Fewer Component 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 Component in Decoupling:
Up to 1:7
replacement of MLCC in power delivering 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
•
Matched Y-caps:
Two tightly matched line to ground
capacitors in one device
•
Superior Balance:
Temperature and voltage
variations balanced of two Y-caps
•
Aging Reliability:
Aging effects are equal on two Y-
caps
