X2Y FILTER & DECOUPLING
CAPACITORS
X2Y® filter capacitors employ a unique, patented low inductance design featuring two balanced
capacitors that are immune to temperature, voltage and aging performance differences.
These components offer superior decoupling and EMI filtering performance, virtually eliminate
parasitics, and can replace multiple capacitors and inductors saving board space and reducing
assembly costs.
ADVANTAGES
APPLICATIONS
• One device for EMI suppression or decoupling
• Replace up to 7 components with one X2Y
• Differential and common mode attenuation
• Matched capacitance line to ground, both lines
• Low inductance due to cancellation effect
• FPGA / ASIC / µ-P Decoupling
• DDR Memory Decoupling
• Amplifier FIlter & Decoupling
• High Speed Data Filtering
• Cellular Handsets
