N2 - We have developed the common mode choke coils made of a kind of new nanocrystalline soft magnetic Fe-M-B (M = Zr, Nb, Hf) based alloys, "NANOPERM®," with high saturation magnetic flux density above 1.5 T as well as excellent soft magnetic properties. The very low remanence ratio, which is necessary to obtain good pulse voltage attenuation characteristics of the common mode choke coils, has been obtained by annealing treatment in a static transverse magnetic field. Insertion loss and the pulse voltage attenuation characteristics of the NANOPERM® common mode choke coil have been found to be superior to those of the choke coil made of MnZn-ferrite. Furthermore, the NANOPERM® common mode choke coil exhibits stable inductance characteristics against temperature change. It can be concluded that NANOPERM® is suitable for a core material of the common mode choke coils.
