Common mode choke cores using the new Fe-based alloys called ''FINEMET'' composed of ultrafine grain structure were developed. These new cores show high attenuation to high-voltage pulse noises and good attenuation characteristics over a wide frequency range. Accordingly, the new cores are expected to be applied in many applications as line filters for electronic devices.
