Johanson Dielectrics X2Y® Filter Capacitors

Johanson Dielectrics X2Y® Filter Capacitors are designed with a unique, patented low-inductance construction featuring two balanced capacitors that are immune to temperature, voltage, and aging-induced performance differences. One X2Y Filter Capacitor from Johanson provides EMI suppression or decoupling, replacing multiple capacitors and inductors, saving board space and reducing assembly costs.

Features

  • One device for EMI suppression or decoupling
  • Replace up to seven components with one X2Y
  • Differential and common mode attenuation
  • Matched capacitance line to ground, both lines
  • Low inductance due to cancellation effect

Applications

  • Amplifier filter & decoupling
  • High-speed data filtering
  • EMC I/O filtering
  • FPGA / ASIC / µ-P decoupling
  • DDR memory decoupling
