Claims

[Claims for Utility Model Registration] Ring-shaped magnetic core 1 placed on the surface of printed board 5
and a desired number of winding elements 10 whose starting ends 10a and terminal ends 10b of the inverted U-shaped tips are inserted and soldered into radially parallel through holes so that the main body grips the magnetic core 1. A plurality of pattern elements 20 that sequentially connect the terminal end 10b of the winding element 10 in the front turn and the starting end 10a of the winding element 10 in the rear turn, and the starting end 10a of the winding element 10 in the first turn. A toroidal coil characterized in that it consists of one input/output pattern 7A connected to the winding element 10 of the last turn, and the other input/output pattern 7B connected to the terminal end 10b of the winding element 10 of the last turn.
