Abstract
This paper described the application of an Fe-based nanocrystalline ribbons to a noise filter in the 1 MHz〜1 GHz frequency range. A 10-μm-thick Fe_<76.2>Cu_<1.0>Nb_<2.0>Si_<14.9>B_<5.9> amorphous ribbon was converted into an Fe-based nanocrystalline ribbon by annealing at 500℃〜600℃ for 10min. This ribbon exhibited high permeability and high impedance charactersitics. It was confirmed that an Fe-based nanocrystalline ribbon noise filter with a 1/18th that of a conventional filter (ferrite core) exhibited the same noise attenuation.
