X2Y EMI FILTER CAPACITORS
X2Y® filter capacitors employ a unique, patented design
in which common shielding electrodes form a Faraday
Cage around traditional capacitor electrodes. This
creates two matched or balanced capacitors that are
immune to temperature, voltage and aging performance
differences.
These components offer superior filter and decoupling
performance and virtually eliminate parasitics. One X2Y®
filter capacitor can replace multiple capacitors and
inductors saving board space and reducing assembly
costs.
X2Y® filters provide optimal filtering and noise
suppression solutions for DC motors, broadband filtering,
filtered connectors, fiber optic and cellular applications.
