    How can I create a Simetrix model of a EMI filter?
    In particular, I wonder how to import a common mode choke into the schematic.
    Alternatively I'm considering to import a S-parameter model of the EMI filter, but I don't know how.
    Thank you for your replies.

    The common mode choke can be modeled by a coupled inductor. Observe the winding start of both inductors so the differential mode components cancel and common mode components are blocked.

    This is from the online help. I have no experience with Simetrix.
