  • Patent number: 7656647
    Abstract: Surface mount electrolytic capacitors are provided with anode and cathode terminations having respective first termination portions provided on the bottom surface of a molded package in a generally coplanar configuration. A second cathode termination portion is bent in a generally perpendicular fashion to the first cathode termination portion and may then be adhered to the external cathode layer of a capacitor body. A second anode termination portion is bent in a generally perpendicular fashion to the first anode termination portion and may then be welded to an anode wire connected to and extending from the capacitor body. An insulation pad may be provided between the first anode termination portion and the capacitor body to prevent device shorting. A planar termination frame may be provided to form the electrolytic capacitors of the present subject matter.
    Type: Grant

  • Patent number: 6611421
    Abstract: Non-polar tantalum capacitors and non-polar tantalum capacitor arrays with compact designs are provided. The reduced volume and footprint of the capacitors and arrays in turn reduces the amount of space required in any device in which they are used. In addition, the cost of materials is reduced, and the manufacturing is simplified. Some embodiments of the present invention provide an electromechanical connector between the anode rods of each pair of polar tantalum capacitors, and insulation between the remainder of the capacitor bodies, thus providing a non-polar tantalum capacitor. These non-polar capacitors are mechanically connected to make a non-polar tantalum capacitor array. Other embodiments of the present invention provide for physically connecting the anode rods of the polar capacitors. An insulating encapsulant around the connected rods and between the polar capacitor bodies also holds the capacitors and capacitor arrays together.

  • Patent number: 4409642
    Abstract: A portion of the anode lead of a solid electrolyte capacitor is offset so that the remaining portion of the anode lead is coaxial with the anode riser, and these and the cathode lead are coplanar. The offset portion of the anode lead is bent transversely, and the riser is connected to this transverse. Preferably, the anode lead and the cathode lead are of different diameters.
