止フイルタ。[Claims for Utility Model Registration] (1) A conductor has two end faces in two recesses sandwiching the central leg of a so-called E-type magnetic core, which has one central leg and two side legs sandwiching the central leg. The center leg is provided with a groove that accommodates the chip capacitor that spans both end faces, and one end face and the board mounting surface have two recessed conductors and a chip capacitor electrode surface.
The end faces of the other board-mounted terminal electrodes are electrically insulated from the electrodes of the two recessed conductors and the chip capacitor, and the two E-shaped magnetic cores are integrally formed into one electrode. Noise prevention is achieved by bonding the recesses facing each other, making one end of the chip capacitor a ground terminal, forming an inductor with the conductors in both leg recesses, and configuring a T-shaped filter by connecting both leg conductors to signal lines respectively. filter. (2) In the scope of the utility model registration claim described in paragraph 1, in order to construct a noise prevention filter, the surface of the magnetic material to which the conductor is attached is coated with a film of electrical insulation in advance if the material has a high initial magnetic permeability. After that, a noise prevention filter was constructed by attaching a conductor. (3) A noise filter comprising one E-shaped magnetic core and one I-shaped magnetic core in a noise filter as claimed in the utility model registration claims set forth in paragraphs 1 and 2.
