Ed, unfortunately I did not measure that parameter. Most of the readers
are just interested in dB attenuation so I didn't measure the complex
impedance. However, the inductance of the CMC is responsible for the CM
attenuation. Core losses and conductor resistive losses are minimal. So,
most of the CM attenuation is due to the inductance of each bifilar
winding. It's the bifilar winding that forces through magnetics in the
core, good DM match on the balanced side of each CMC.

Great work Dave.
Thanks for your continuing contribution to our great hobby.
Do you have in your stash a piece on conversion of dB attenuation to Zs=
Rs + Xs ?
