Common-mode current chokes CMCC OK2ZAW
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).
Common-Mode Current insulator High curren insulation Coax impedance 50 or 75 Ohm Controller (analog) wires insulator
Good quality PTFE coax cable Low insert loss
- Quality PTFE SO-239 or N connector or F.
