摘要： A solid electrolytic capacitor containing a capacitor element is provided. The capacitor element contains an anode body that contains tantalum, a dielectric that overlies the anode body; and a solid electrolyte that overlies the dielectric. The solid electrolyte includes an intrinsically conductive polymer containing repeating thiophene units. Further, the capacitor exhibits a dielectric strength of about 0.6 volts per nanometer or more. The capacitor also exhibits a charge-discharge capacitance after being subjected to 3,000 cycles of a surge voltage and an initial capacitance prior to being subjected to the surge voltage, wherein the ratio of the charge-discharge capacitance to the initial capacitance is from about 0.75 to 1.
