Abstract:
A surface-mount capacitor includes a multilayer capacitor structure formed by laminating plate-like capacitor elements each having anode lead portions at opposite ends thereof and a cathode portion at the center, an anode terminal connected to each anode lead portion via a strip-like plate, and a cathode terminal connected to the cathode portion. The anode and the cathode terminals and have a flat shape and are formed on a common plane as a substrate-mounted surface. A mold resin case has a bottom portion filling a gap between the anode and the cathode terminals and mechanically connecting the anode and the cathode terminals and sidewalls substantially perpendicular to the substrate-mounted surface. The anode and the cathode terminals have upper surfaces exposed on an inner bottom surface of the mold resin case to be connected to the anode lead portions and the cathode portion.
