ABSTRACT:
A method of making a tantalum capacitor molds a plug in situ on one end of an anode and about a connector which projects through the molded plug for electrical connection with the anode. A spacer is molded in situ on the other end of the anode. During molding, the plug and spacer form a permanent bond with the anode to form a core unit comprising the plug, connector, anode, and spacer. Ribs extending along sides of the anode connect the plug to the spacer to improve the physical integrity of the core unit. The core unit is then inserted in a can which is filled with a fluid electrolyte and crimped about the plug to seal the can. The preferred practice of the method additionally bonds the plug to the can and connector to hermetically seal the capacitor. A capacitor made according to the preferred method then comprises the core unit hermetically sealed in the electrolyte filled can.
