Common Mode choke is not exactly optimal for Differential Mode noise, to 
express me in that way.

But to suppress DM noise, is it possible to use a CM choke by connecting one 
wire on the opposite choke terminal? Would the DM flux in the core add and not 
cancel as regular use of CM choke?

 

I hope my explanation is understandable :-)

 

Best regards

Amund
