If you run DC through them (unbalanced) they should probably have a gapped
core as well..

Subject: Re: [EE] Common mode chokes

Mohit,
You may not be able to use them at all. As they are wound as common
mode, if you don't run the dc current though them in both directions
(i.e. go and return), they are likely to saturate and present a much
lower effective inductance. If you are running a lot less than 10A you
could try it by just using one winding - or connecting both windings
in parallel but connected so that both winding "starts" are connected
to the same point - if that makes sense.
