Patent ID: 7764143

Claim:
An electronic part having a base member constructed by joining a dielectric portion and a magnetic portion, wherein a passband is a band of 76 to 108 MHz or a part thereof, and attenuation from 200 MHz to 6 GHz is not less than 10 dB, wherein said base member has a dimension of not more than 2.0 mm×1.25 mm×1 mm, and said electronic part is usable for a portable device, and wherein a magnetic material, which forms said magnetic portion, is ferrite containing a main component of a composition in which NiO is 31 to 42 mol %, ZnO is 2 to 10 mol %, Fe 2 O 3 is 43 to 48 mol %, Co 3 O 4 is 0.5 to 3 mol %, and CuO is 10 to 14 mol %, said ferrite having an initial magnetic permeability of not less than 10 at a frequency of not more than 150 MHz.
