  • Patent number: 8559166
    Abstract: A solid electrolytic capacitor includes a capacitor element, an anode lead frame, a cathode lead frame, and a mold resin portion. The anode lead frame includes an anode terminal portion and a rising portion, and the anode terminal portion is exposed at the bottom surface of the mold resin portion. The rising portion is formed integral with the anode terminal portion, and rises to the anode portion. In the rising portion, a through hole is formed. The cathode lead frame includes a cathode terminal portion, a pair of side surface portions and a step portion. Thus, a solid electrolytic capacitor allowing highly accurate and reliable attachment of the capacitor element to the lead frame without using any additional member is provided.
    Type: Grant

  • Patent number: 7283352
    Abstract: A portion of an anode lead frame 3 of a solid electrolytic capacitor 1 is bent to form a protruding portion 4 that protrudes toward an anode lead 20. The protruding portion 4 includes a first horizontal portion 41 positioned higher than and substantially parallel to the anode lead 20, a second horizontal portion 40 contacting the anode lead 20, a sloping portion 42 linking the inner end of the first horizontal portion 41 with the outer end of the second horizontal portion 40, and an auxiliary bent portion 43 bent upward from the inner end of the second horizontal portion 40 and substantially symmetrical with the sloping portion 42. A contact surface 46 of the second horizontal portion 40 with the anode lead 20 is formed flat, and a surface 47 of the second horizontal portion 40 on the opposite side to the contact surface 46 is formed with a rounded curvature.
