Coupled Inductor vs Common Mode Choke vs CT? | All

Again, this is due to the storage of energy in the air gap(s). High permeability cores for common mode chokes produce high inductance for the common mode signal (noise). The whole idea of the thing is that the the differential mode currents produce equal and opposite magnetic flux so the net low frequency flux is "ideally" zero.
