Abstract

PURPOSE:To combine a relatively few types of magnetic rings and to form many types of inductance elements by superposing a plurality of magnetic rings having different permeabilities to each other to form a core. CONSTITUTION:A core is formed by superposing annular magnetic rings 1a, 1b of the same shape. The rings 1a, 1b have different permeabilities to obtain different frequency characteristics in combination. The core 1 is contained in an insulation case 5 made of two pieces, the core 1 is interposed to be held between the two pieces, and the rings 1a, 1b are brought into pressure contact with each other. Further, coils 6, 7 form different inductances, and a separator 8 separates both the coils. Thus, many types of inductance elements can be formed with relatively little types of the magnetic rings.
