EMI FILTER CAPACITORS
X2Y
®
filter chips employ a unique patented approach which
provide simultaneous line-to-line and line-to-ground filtering
via a matched or balanced pair of capacitors. Another
advantage of the matched capacitor design is the
elimination of temperature, voltage and aging effects.
X2Y
®
filters provide an optimal solution for many filtering
applications and can replace a combination of discrete
capacitors and inductors; saving significant board space
and reducing assembly costs.

DVANTAGES
G
• Replaces two or three capacitors with one device
• Matched capacitance line to ground on both lines
• Low inductance due to cancellation effect
• Capacitance line to line
• Differential and common mode noise attenuation
• Reduces board area required for filtering
• Effects of temperature variation eliminated
• Effect of aging equal on both lines
