RX - Common-mode current choke for coax and controller cable

Noise Suppression by Common Mode Choke Coils(Edit)

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).

Example (Edit)

Common-mode current isolation for coax(Edit)

- for 50 Ohm RG-316 coax cable 10 turns

• bigger pic 1 to 50 MHz
• bigger pic 0,1 to 2,5 MHz

Insert LOSS of Common-mode current choke (CMCC)(Edit)

- for 50 Ohm RG-316 coax cable 10 turns

• bigger pic

Common-mode current isolation for controller cable(Edit)

- on small core inductors

bigger pic 0,5 to 50 MHz

bigger pic 0,1 to 2,5 MHz
