FINEMET® common mode choke cores are made of a nanocrystalline soft magnetic material that Hitachi Metals developed as a world first.
Conduction noise often causes serious malfunctions in onboard electronic components. With more electronic components being installed in cars, conduction noise is becoming a more
serious issue for safe driving. Compared to conventional products with Mn-Zn ferrite cores, FINEMET® has higher magnetic permeability and magnetic flux density.
It results in realizing size and weight reductions of
automotive electronic components.
