This is to use at the inputs of a mic preamp, for -hopefully- CMRR enhancement.
Is this, good ? https://www.mouser.fr/datasheet/2/410/media-346070.pdf
It is not specified as a CMC, but it has 1:1 turn ratio, is small, is specified over 20Hz 50KHz
I was unable to find Common Mode Chokes, clearly made for audio.
All, I have found are for power supply lines and do not specify anything about audio. Those on ferrite -a magnetic circuit far from linear-, are lickely when used on audio signals, THD killers.
Could be I missed the right stuff, where is it ?
EDIT From Triad Magnetics too, could this CMC for power lines, be good for audio ?
A 10mH choke. https://www.mouser.fr/datasheet/2/410/C ... 154072.pdf

Re: Common mode choke
There's a thread here: viewtopic.php?f=6&t=490
Have a look at these:
Coiltronics VersaPac Inductors
https://proaudiodesignforum.com/images/ ... uctors.pdf
Coiltronics VersaPac VP2H
or these:
Coilcraft "Tip and Ring" Common Mode Chokes
https://proaudiodesignforum.com/images/ ... Chokes.pdf
I think I have samples of both and may have discussed these in the Line Input thread.
I used the Tip and Ring choke in the Heathkit IG-18 to quieten the switching power supply.
