  • Planar coil component, method for winding end connection thereof and resonance transformer
    Patent number: 7449986
    Abstract: A planar coil component includes terminal metal fittings that include a crimping part, a terminal part, and a junction, and a bobbin on which a winding is wound. The bobbin has a terminal board including insertion holes. The terminal part is inserted from an upper surface of the terminal board into the insertion holes with the junction exposed, so that the terminal part projects from a bottom surface of the terminal board, each end of the winding is inserted into the crimping part through a slot in the bottom surface of the terminal board, and crimped. The winding is one of a litz wire, a stranded wire, and a parallel wire, and welded at an end tip and connected to the terminal metal fitting.
