<p>PROBLEM TO BE SOLVED: To provide a wound part with high performance for easily realizing formation and winding on a thin core. SOLUTION: This wound part is constituted by combining an I-shaped core 2, U-shaped cores 1 jointed with the side faces, and spacers 3. This wound part is assembled by winding a coil 4 around the U-shaped cores 1, and fixing the spacers 3 between the U-shaped cores 1 and the I-shaped core 2. Thus, leakage inductance can be adjusted easily by adjusting the thickness of the spacer 3. The U-shaped core is constituted of Ni-Zn ferrite of 49.5 mol% Fe2O3/24.5 mol% NiO/26.6 mol$% ZnO with an electrical resistivity of 1×1010Ωcm. The I-shaped core is constituted of a Mn/Zn ferrite made of 52.7 mol% Fe2O3/39.3 mol% MnO/8.0 mol% ZnO with electrical resistivity of 1.4×103Ωcm.</p> |
