Abstract

We have developed a choke coil made of new nanocrystalline soft magnetic Fe-M-B (M=Zr, Nb) alloys ("NANOPERM™" material) which exhibit high saturation magnetic induction (B_s), above 1.5 T, excellent soft magnetic properties and zero magnetostriction. A choke coil made of NANOPERM™ material exhibits good dc bias characteristics of inductance because of the high B_s. Furthermore, the choke coil made from NANOPERM™ material showed 1/3rd the temperature rise shown by a core made from Fe-Si-B amorphous alloy. The low core loss and high B_s of NANOPERM™ material allow the reduction of the core size. It is concluded that NANOPERM™ is suitable as a core material for choke coils.
