  • Patent number: 6791444
    Abstract: A chip inductor is made up of a coiled conducting wire and a magnetic member which is formed by sintering and in which the coiled conducting wire is embedded. Both end portions of the coiled conducting wire are exposed to both end surfaces of the magnetic member. External electrodes are formed with conducting thin films and are connected to respective end portions of the coiled conducting wire. An inorganic material is interposed in a clearance between winds of both end portions of the conducting wire and external surfaces of the magnetic member and a clearance between adjoining winds of the conducting wire.

  • Patent number: 6061227
    Abstract: The object of the present invention is to provide a multilayer LC complex component which is capable of improving reliability by reducing frequency of cracks and achieving better strength, especially resistance against flexure thereof. In an embodiment of the present invention, two patterns of conductors for capacitor R1 and R2 are stacked alternately, and conductors for capacitor R1 are connected to each other through via holes R3 and R4. Capacitor 30 is connected to inductor 12 through via hole D3 which passes through aperture R5 formed in conductor for capacitor R2. As there are plural pillars of via hole formed in the right, left and central part of the present invention, this structure achieves improvement of strength of the central part thereof wherein most of stresses caused by flexure and bending concentrate.

  • Patent number: 5669134
    Abstract: A winding core is formed by extruding a kneaded material which is obtained by kneading a powdered magnetic material and a binder. A conducting wire is wound around the winding core in a coiled manner. An external cover element is formed by extruding the kneaded material to enclose the winding core, and the winding core and the external cover element are sintered. The semimanufactured product obtained by the above steps is cut into a predetermined length to thereby obtain a plurality of chip inductor main bodies. An external electrode is formed on each of end surfaces of the respective chip inductor main bodies such that the external electrode is connected to each of end portions of the conducting wire, the end portions being exposed to both end surfaces of the respective chip inductor main bodies.

  • Patent number: 5544410
    Abstract: Electronic parts, such as tip inductors may be formed by molding a first molded component as a core by kneading a magnetic material, such as ferrite powder, and a binder, such as resins, spirally winding a conductive material on the periphery of the first molded component with a constant winding pitch, molding a second molded component by covering the periphery of the conductive material as well as the first molded component with a kneaded mixture of a magnetic material, such as ferrite powder, and a binder, such as resins, to form a cover component, integrally sintering both of the first molded component and the cover component, cutting the second molded component into tips of desired length, to thereby partially expose the conductive material out of both end surfaces of the second molded component. Further, terminal electrodes may be fixed to said conductive material at each of the end surfaces of the second molded component where said conductive material of said tips is partially exposed.
