Latest Patents

Iguchi holds a patent for a wire wound electronic part. This invention includes a ferrite core that comprises ferrite with a columnar wire wound core and flanges formed at both ends. The design features a coil conductor wound around the wire wound core of the ferrite core, along with at least a pair of terminal electrodes that have a copper conduction layer on the outer surface of the flange. The unique aspect of this invention is that both ends of the coil conductor are conductively connected to the terminal electrodes. The terminal electrode is created by coating an electrode paste containing copper powder and glass frit onto the outer surface of the ferrite core, followed by a heat treatment. This process results in a reaction layer at the boundary between the ferrite core and the copper conduction layer. Notably, the terminal electrodes exhibit peel strength comparable to that of existing silver terminal electrodes, without the need for a plate layer.
