<p>PROBLEM TO BE SOLVED: To reduce a PCV (core loss) value of a ferrite core to be used for a part to be charged. SOLUTION: This electrical equipment 1 applicable to non-contact charger has a part 2 to be charged, constituted of a ferrite core 3 including 53 mol.% of Fe2 O3 or less, 10-20 mol.% of NiO, 22-35 mol.% of ZnO, and 4-7 mol.% of CuO and a coil 4 wound around the ferrite core 3. In this way, a PCV value can be reduced, and a part to be charged can be charged efficiently by limiting the composition of the ferrite core. Thus, it is possible to provide an electrical equipment applicable to non-contact charger with high performance in which a charging time can be shortened.</p> |
