  • Patent number: 7525790
    Abstract: A solid electrolytic capacitor with face-down terminals includes a capacitor element having an anode lead drawn out therefrom in an offset manner, an anode terminal, a cathode terminal, and an insulating casing resin. At a rectangular mount surface having a first and a second side parallel to each other and forming an outer bottom portion, four terminal exposed portions are provided such that a terminal pair composed of the two terminal exposed portions are located at the first side and a terminal pair composed of the other two terminal exposed portions are located at the second side. The two terminal exposed portions located at the first side serve as mount-surface exposed portions of the anode terminal and the cathode terminal, while, the two terminal exposed portions located at the second side serve as dummy terminals that are not electrically connected to the capacitor element.

  • Patent number: 7320924
    Abstract: A chip-type solid electrolytic capacitor comprises capacitor elements. A cathode terminal comprising a plate-like conductor is interposed between cathode layers of the capacitor elements. The capacitor elements are bonded to each other by a bonding agent such as a solder or a conductive adhesive. The cathode terminal is provided with a through hole formed at a portion to be brought into contact with each of the capacitor elements. Bonding surfaces of the capacitor elements are directly connected at the through hole.

  • Patent number: 6816358
    Abstract: A chip-type solid electrolytic capacitor having two capacitor elements using a valve metal and laminated in a direction perpendicular to a mounting surface to be mounted on a substrate. A pair of anode lead wires are extracted on one side from anode members of the capacitor elements in parallel to the mounting surface. The anode lead wires are connected to two branches of an anode terminal portion, respectively. A cathode terminal is connected to cathode layers on dielectric oxide films of the anode members. The solid electrolytic capacitor is encapsulated in an encapsulating resin with the anode terminal and the cathode terminal partially exposed. The branches of the anode terminal portion are configured so that they overlap each other by rotation of 180° around a center line.
