Solid electrolytic chip capacitor with improved terminals

Abstract

In a solid electrolytic chip capacitor having a capacitor element of the type manufactured by laminating a metal oxide semiconductor layer and a cathode layer one after another on an anode electrode made of a sinter of a valve metal, which anode electrode has an anode lead made of a valve metal, and has a dielectric oxide film on the surface thereof, an anode terminal is connected to an upper portion of the anode lead, while a cathode terminal is connected to an upper portion of the cathode layer. The capacitor element as well as a portion of the anode terminal and a portion of the cathode terminal are embedded in a resin casting, and the anode and cathode terminals are respectively drawn from both sides of the casting, and bent so that exposed portions of the anode and cathode terminals are situated along the sides and the lower surface of the casting. The cathode terminal has a U-shaped portion for receiving the capacitor element, while elongate slots may be made in both terminals. A window may be made in the anode terminal so as to ensure welding with respect to the anode lead.
