Overview

FINEMET® common mode choke cores
FINEMET® common mode choke cores - two

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.


Applications

  • Hybrid electric vehicles (HEV), electric vehicles (EV), and plug-in hybrid electric vehicles (PHEV)
