Solid electrolytic capacitor having thermal compensation |
摘要 |
An aspect of the present invention provides a solid electrolytic capacitor that comprises: an anode mainly formed of a valve metal or an alloy thereof; an anode lead terminal a part of which is buried in a side surface of the anode; a dielectric layer formed on surfaces of the anode and mainly formed of an oxide; a conducting polymer layer formed on the dielectric layer; a cathode layer formed on the conducting polymer layer on an outer circumferential surface of the anode, the cathode layer comprising: a carbon layer; and a silver paste layer formed on the carbon layer; a thermal expansion layer provided on the side surface of the anode and on a part of the outer circumferential surface continuing from the side surface; and a rein outer package provided to cover the anode, dielectric layer, cathode layer, and thermal expansion layer, wherein a thermal expansion coefficient in a temperature range lower than a glass transition temperature of the thermal expansion layer is larger than that of each of the silver paste layer and the resin outer package. |
