摘要： In a noise filter, an input side of a signal-line lead is inserted in a first substantially cylindrical ferrite bead, and an output side of the signal-line lead is inserted in a second substantially cylindrical ferrite bead. An input side of a ground lead is inserted in a third substantially cylindrical ferrite bead. The signal-line lead is inserted in a feedthrough capacitor such that the feedthrough capacitor is adjacent to an output side of the second substantially cylindrical ferrite bead. A multilayer capacitor is electrically coupled between the signal-line lead and the ground lead such that the multilayer capacitor is adjacent to an output side of the first substantially cylindrical ferrite bead and adjacent to an output side of the third substantially cylindrical ferrite bead. Each of an end of the signal-line lead and an end of the ground lead is flat, bent along an outer surface of a base member, and defines a surface-mount external terminal.

摘要： A noise filter includes a capacitor having a hot side input terminal, a hot side output terminal, a ground side input terminal, and a ground side output terminal. A circuit board includes a hot side input electrode connected to the hot side input terminal, a hot side output electrode connected to the hot side output terminal, a ground side input electrode connected to the ground side input terminal, and a ground side output electrode connected to the ground side output terminal. The impedance of the ground side input terminal seen from the ground side output electrode is larger than both the impedance of the ground side output terminal seen from the ground side output electrode and the impedance of the hot side output terminal seen from the ground side output electrode. For this purpose, a stray capacitance formed between the ground side input electrode and the ground side output electrode is reduced by increasing a gap therebetween. Accordingly, excellent noise-reducing characteristics are provided.

摘要： A bead inductor has excellent productivity and increased reliability in the connection between an internal conductor and external terminals. A method for manufacturing such a bead inductor includes the steps of forming an internal conductor and the external terminals as an integral, unitary member such that the external terminals are disposed at both ends of the internal conductor and electrically connected thereto; positioning the integral, unitary member in a metallic mold; and molding a resin material or a rubber material including a powdered magnetic substance in the metallic mold so as to embed the internal conductor therein.

摘要： A method of producing a bead inductor includes the steps of forming an outer portion outside of a conductor coil, and forming a molded body with the conductor coil embedded therein. The outer portion is formed outside of the conductor coil by disposing the conductor coil in a cavity defined by first and second mold portions, with first and second gates formed in the first mold portion, inserting first and second spacer pin portions, which define a spacer pin which passes through the conductor coil and extends to and closes the second gate, and supplying material containing magnetic powder into the mold cavity from the first gate. The molded body is formed by closing the first gate after the formation of the outer portion, and supplying from the second gate material containing magnetic powder into a space formed by removing the spacer pin portions.

摘要： A method of manufacturing a bead inductor prevents deformation of a metal coil or dislocation of the axis position of the metal coil caused by injection pressure at the time of injecting a molten resin material from a gate. A coil is fitted onto a coil supporting pin provided on a first lower mold used for injection molding in a cavity of the mold such that the inner periphery of the coil is in close contact with the coil supporting pin. A molten, resin material is injected into the cavity. Then, the coil supporting pin and the first lower mold are removed from the molded product, and a second lower mold without a coil supporting pin is provided for replacing the first lower mold. A molten resin material is injected into the space which had been occupied by the coil supporting pin. After removing the hardened resin molded product from the mold for injection molding, the end parts of the coil are cut so as to be exposed.
