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 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.
