SOLID ELECTROLYTIC CAPACITOR WITH SMALL LEAKAGE CURRENT AND METHOD OF MANUFACTURING THE SAME
摘要:
A solid electrolytic capacitor includes an anode formed of a valve metal and having a roughened surface layer at a surface thereof, a dielectric layer formed of a valve metal oxide and formed on the anode, a cathode formed of a conductive polymer layer formed on the dielectric layer, an anode lead formed adjacent to and integrally with the anode, and a resist formed of an insulating material and delimiting the anode and the anode lead. The anode and the anode lead have a first stepped portion having both surfaces each cut in a thickness direction and covered with the resist, and the anode lead has a second stepped portion having both surfaces each cut deeper in the thickness direction than the first stepped portion.
