How to design a CMC (Common Mode Choke) footprint to allow no-pop solution
In these situations for prototyping I do something like this:



You cut the traces on the PCB if you need to install the choke. That way you don't impedance problems from soldering wires. The problem with this setup is once you cut the PCB traces, you can't go back. Another way to do this would be to put 0 ohm resistors in series with the choke. Or you could use 0 ohm resistors if you select them the same size as the choke gap.
