For most of the switching power supply, EV electronic control, electric drive and other power supplies will encounter electromagnetic compatibility (anti-EMI interference) problems, with nanocrystalline coiled common-mode core made of common mode inductor is a very good solution to the problems encountered in this regard. Nanocrystalline material itself has the advantages of high permeability, high magnetic induction strength, high temperature stability, which traditional ferrite does not have, and the flat wire common mode inductor made of nanocrystalline material has the advantages of high inductance, high impedance, small size, and automation of winding.
