Abstract: Methods of manufacturing a hermetically sealed wet electrolytic capacitor and a hermetically sealed wet electrolytic capacitor are described. A method of manufacturing a wet electrolytic capacitor includes forming a cathode of the capacitor by forming a case comprising a metal substrate, the metal substrate having an alloyed surface, depositing a smooth film comprising palladium and copper as a tacking layer on the alloyed surface of the metal substrate, and depositing a rough, high surface area layer on the tacking layer to achieve a high capacitance cathode. A first terminal is electrically connected to the cathode. An anode is formed. A second terminal is electrically connected to the anode. An electrolytic solution is disposed within the case, and the case is hermetically sealed.

Abstract: A wet electrolytic surface mount capacitor has a body defining an interior area and having a fill port formed through a wall of the body. A capacitive element is positioned in an interior of the body and is isolated from the body. A surface mount anode termination is in electrical communication with the capacitive element and isolated from the body. A surface mount cathode termination is in electrical communication with the body. An electrolyte is contained in the interior area of the body, and is introduced into the interior area of the body through the fill port. A fill port plug is positioned adjacent the fill port. A fill port cover compresses the fill port plug against the fill port to seal the fill port, and may be welded in place. A method of forming the capacitor is also provided.
