  • Patent number: 8139344
    Abstract: A solid electrolytic capacitor has a capacitor body formed from a pressed anode, a dielectric layer and a solid electrolyte layer. An anode lead extends from anode pellet and is electrically connected to an anode termination. The outer surface of the capacitor body forms a cathode that is electrically connected to a cathode termination. Base anode and cathode termination portions are coplanar and connected with a recessed leadframe channel. A capacitor element is attached to the anode and cathode termination portions and encapsulated. The recessed leadframe channel is removed to isolate the anode and cathode terminations on a single mounting surface, leaving a surface groove formed between the anode and cathode terminations.

  • Patent number: 8075640
    Abstract: A surface-mountable electrolytic capacitor with improved volumetric efficiency includes an electrolytic capacitor element, anode and cathode terminations, an encapsulation material and external terminations. The capacitor element has first and second opposing end surfaces and an anode wire extending from the first end surface that is electrically connected to a first anode termination portion. A first cathode termination portion is conductively adhered to a surface of the capacitor element, and a second portion is perpendicular to the first portion and parallel to the second end surface of the capacitor element. Encapsulating material surrounds the capacitor element to form a device package that is subsequently diced to improve volumetric efficiency and optionally expose the anode and cathode terminations on opposing end surfaces. First and second external terminations may be formed over the exposed portions of anode and cathode terminations to wrap around to one or more given surfaces of the device package.

  • Patent number: 7468882
    Abstract: An integrated capacitor assembly that offers improved performance characteristics in a convenient and space-saving package is provided. More specifically, the capacitor assembly contains a first solid electrolytic capacitor element and second solid electrolytic capacitor element positioned adjacent to the first solid electrolytic capacitor element. The first and second solid electrolytic capacitor elements each contain an anode formed from a valve metal composition having a specific charge of about 70,000 ?F*V/g or more, the anode having a thickness of from about 0.1 to about 4 millimeters. A thermally conductive material is positioned between the first and second solid electrolytic capacitor elements and electrically connected thereto. The thermally conductive material has a coefficient of thermal conductivity of about 100 W/m-K or more at a temperature of 20° C. A case encapsulates the first and second solid electrolytic capacitor elements.
