PURPOSE:To display the performance of a ferrite core sufficiently by winding a single layer solenoid winding around the rod-like ferrite core at a part more than a specific length out of the whole length and winding the center part with higher density as compared to the right and left winding parts. CONSTITUTION:The single layer solenoid winding 12 is wound around the rod- like ferrite core 11 at a part >=2/3 the whole length with distributed density at both end parts and high density at the center part. In another example, a concentrated winding coil 15a obtained by winding the solenoid coil thickly is wound around the ferrite core 14 at its center and distributed winding coils 15b are wound at both right and left winding parts. |
