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 low profile wet electrolytic capacitor is disclosed. The low profile wet electrolytic capacitor includes an outer case assembly. The outer case assembly is formed by an outer case and outer case cover that is hermetically sealed to the outer case. The outer case assembly includes an interior area. A capacitive element is positioned in the interior area. The capacitive element is isolated from the outer case assembly by a plurality of insulative elements. A connecting tube is positioned perpendicular to and attached to the outer case and the outer case cover and passes through an opening in the capacitive element. An isolated positive lead is positioned on the outer case assembly and is in electrical communication with the capacitive element. A fluid electrolyte is contained in the interior area of the outer case assembly. A method of forming the capacitor and stacked capacitor assemblies is also provided.

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.

Abstract: A capacitor may include a stack assembly. The stack assembly may include a plurality of anode plate members, each having an embedded wire. The anode plate members may be separated by at least one cathode foil sandwiched between separator sheets. A conducting member may electrically connect the embedded wires and may have an externally accessible end portion that is hermetically sealed from the interior of the capacitor. A case covers the stack assembly and may be attached to a cover. The case and cover may enclose the stack assembly within an interior area of the capacitor. The at least one cathode foil may be connected to the case. An electrolyte fluid may be disposed within the interior area of the capacitor. A passage may be provided through a central portion of the stack assembly. A tube, surrounded by insulation, may pass through the passage and may be connected to the cover and the case.
