  • HIGH VOLTAGE SOLID ELECTROLYTIC CAPACITORS USING CONDUCTIVE POLYMER SLURRIES
    Publication number: 20080247121
    Abstract: A method for forming a capacitor including forming an anode from a valve metal; forming an oxide on the anode to form an anodized anode; dipping the anodized anode into a slurry of conductive polymer; drying the intrinsically conductive polymer; and providing external terminations in electrical contact with the anode and the conductive polymer.
    Type: Application
    Filed: May 7, 2008
    Publication date: October 9, 2008
    Inventors: Yongjian Qiu, Randy S. Hahn, Keith R. Brenneman
