ABSTRACT:
A dampened choke coil structure having a ferromagnetic core and a winding of wire disposed about the core to form a choke coil. A second winding of substantially higher resistance material is wound generally parallel to the choke winding either inside or outside thereof. The number of turns of the two windings differ by more than 25%. In this way, parasitic capacitances are caused to have a decreased effect on the choke coils.
