Abstract

An inductance device according to the present invention, which is for use in power supply units, is constructed in such a manner that a slit 3 is provided in one side of a polygonal cylindrical ferrite core 1 in the same direction to a hollow portion 2 to form an open magnetic path, and a belt-like conductor 4 is inserted through the hollow portion 2, so as to minimize the dimensions, have an inductance value not more than 1 &mgr;H, and hold DC overlapping characteristic flat even if high current flows.
