Common Mode Inductors

Triad Magnetics Common Mode Inductors are used for EMI suppression in power supplies. These inductors meet VDE, IEC, UL, and CSA requirements and can also be used to provide differential mode filtering. Common Mode Inductors from Triad minimize interference caused by high frequency switching power supplies.
