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).
Main functions:
Common-Mode Current insulator High curren insulation Impedance 50 or 75 Ohm
Good quality PTFE coax cable Low insert loss - Quality PTFE SO-239 or N connector or F.
Parameters:
- Low insert loss < 0,2 dB
- Common-mode isolation better than 30 dB (7 MHz and lower)
- RF power up to 100 W
The measured values
 Common-mode current insulation - 1 to 50 MHz |
 Common-mode current insulation - 0,1 to 2,5 MHz |
 Insert loss |
