  • Patent number: 7319582
    Abstract: A multilayer capacitor includes first and second internal electrodes that are opposed to each other so as to generate an electrostatic capacitance and have a capacitance generating portion functioning to generate the electrostatic capacitance, terminal connecting portions connected to corresponding external terminal electrodes, and extended portions connecting the capacitance generating portion to the terminal connecting portions. The extended portions are narrower than the capacitance generating portion and the terminal connecting portion and are curved in the direction of their thickness so as to provide a longer effective length. The multi-terminal capacitor is capable of increasing an ESR without adding a separate additional element.

  • Patent number: 7310217
    Abstract: A monolithic capacitor includes a main capacitor unit having first capacitor portions and a second capacitor portion arranged in a direction of lamination, with the first capacitor portion located towards at least one end in the direction of lamination, so that the first capacitor portion is located closer to a mounting surface than the second capacitor portion. The number of pairs of third and fourth lead-out portions for third and fourth internal electrodes in the second capacitor portion is less than the number of pairs of first and second lead-out portions for first and second internal electrodes in the first capacitor portion, so that the first capacitor portion contributes to decreasing ESL while the second capacitor portion contributes to increasing ESR.

  • Patent number: 7303402
    Abstract: The invention relates to a connector for interconnecting an plurality of wiring boards, a method for manufacturing the same, and a wiring board structure employing the connector. The connector has a base member having no conductivity and a conductive wire provided on a surface of the base member, and is arranged so as to be connectable to a wiring board, comprising: a conductive pressing member provided on and protruding from the wire; and a holding member provided on and protruding from a portion in the surface of the base member except where the pressing member is located, the holding member having an affixing surface attachable to the wiring board. The invention can make the wire provided on a surface of the wiring board flat, and therefore it becomes possible to secure the flexibility in designing a wiring pattern of a wiring board.
