The devices you are referring to are RFI suppressors. They are simply little
blocks of ferrite surrounding the wire to add a miniscule (a few hundred
nanohenries at most) amount of inductance to the wire so high frequency
doesn’t get radiated. The frequencies of interest are typically above 10MHz
as required for FCC and CE compliance amongst others. The inductance of these
devices will have very little if any effect on DCC.

JB-
Clearly if they are just for RFI, then that’s not a DCC problem.
Thanks.
