  • Solid-electrolyte capacitor, manufacturing method thereof, and digital signal processing substrate using the solid-electrolyte capacitor
    Patent number: 7365961
    Abstract: A solid electrolytic capacitor includes a planar solid electrolytic capacitor element having anode and cathode portions; anode and cathode terminals; and insulating coating resin. The anode terminal is electrically connected at the top surface thereof to the anode portion. The cathode terminal is electrically connected at the top surface side thereof to the cathode portion. The coating resin integrally coats the capacitor element so as to expose the bottom surfaces of the anode and cathode terminals. The anode and cathode terminals are disposed as close to each other as not more than 3 mm. The anode and cathode terminals have stair steps on both sides thereof and are connected to the anode and cathode portions at joint faces, respectively. The anode joint faces and the cathode joint faces are coated with coating resin. The solid electrolytic capacitor is provided with the anode joint faces and/or the cathode joint faces.
