Description

Common-mode choke coils work as a simple wire against differential mode current (signal), while they work as an inductor against common-mode current (noise).


Using

  • Common-mode filter for coax cable
  • RX antennas, active antennas etc.

Main functions

  • Common-mode current insulator
    • High current insulation
    • Impedance 50 or 75 Ohm
