US 7,352,562 B2 · Surface-mount solid electrolytic capacitor and process for manufacturing same

Abstract

A solid electrolytic capacitor includes a capacitor element 2, an anode lead terminal 3 electrically connected to an anode of the capacitor element, a cathode lead terminal 4 electrically connected to a cathode of the capacitor element, and a package 5 which is made of synthetic resin and hermetically seals the capacitor element. The lead terminals are embedded in the bottom 5a of the package with the lower surfaces of the lead terminals exposed at the bottom surface of the package. The anode lead terminal and the cathode lead terminal are respectively formed with standing pieces 8 and 9 at portions corresponding to side surfaces 5b, 5c of the package, and the standing pieces have respective outer surfaces exposed at the side surfaces of the package. This structure enhances the soldering strength and facilitates the visual inspection of the quality of the soldering.
