摘要： A chip type tantalum capacitor has an insulating resin frame, a pair of substantially flat metal foil terminals bonded to both sides of the frame, at least one of the frame sides having a slit therethrough and open to the outside of the metal foil terminal on the one frame side, the metal foil terminal on the one frame side being a metal selected from the group consisting of copper and nickel. A tantalum capacitor element having a pair of terminals is enclosed in the frame, at least one of the element terminals being a lead wire made of tantalum, the lead wire extending through the slit and outside the metal foil terminal on the one side of the frame and being bent at the outside surface of the metal foil terminal with the bent portion of the lead wire outside the metal foil terminal extending along the surface of the metal foil terminal and being welded to the metal foil terminal surface for being fixed thereto, the other element terminal being electrically connected to the other metal foil terminal. An insulating resin is potted in the space inside the frame and around the capacitor element.

摘要： A method for making an electrolytic capacitor. A valve metal powder of the sponge type is compressed into a compact body and other usual steps including anodization and electrode application are carried out thereon. Mainly due to the use of sponge type valve metal powder, this method makes it unnecessary to carry out the conventionally employed step of sintering the compact body and produces an electrolytic capacitor having properties better than those obtained by the conventional method. This invention also provides an electrolytic capacitor characterized by the use of sponge type valve metal powder and specific lubricant materials.
