Abstract

A chip-shaped 3-lead filter for preventing electromagnetic waves comprises a ferrite device(2) in which lead portions(4,5) is installed by interposing coil winding recesses(6,6') on both sides of a filter body(3) and in which a condenser receiving recess(7) to which a chip condenser(12) is mounted is formed at a center portion of the filter body(3) and in which electrodes(8,8',9,9') are respectively formed on the bottom and upper sides of the filter body(3) and on the lower surface of the lead portions(4,5); an inductance extracting portion(10) in which a copper coil(11) is wound in coil winding recesses(6,6') of the ferrite device(2) and in which one end portion of the copper coil(11) is connected to the electrode(8') formed on an upper side of the filter body(3) and the other end portion thereof is electrically connected to the electrodes(9,9') formed on the lower surface of the lead portions(4,5); a chip condenser(12) which is inserted into the condenser receiving recess(7) formed on the center portion of the filter body and is electrically connected to the electrodes(8,8') coated on the upper and lower sides of the filter body(3); and a resin molding portion(13) which is an insulating epoxy resin and insulates the ferrite device(2).
