Abstract
Disclosed are a hybrid aluminum electrolytic capacitor and a method of producing the same, where the electrolytic capacitor is impregnated in a film repairing fluid. The film repairing fluid includes an organic solvent having a b.p. of 180° C. or more, a small number of an inorganic and/or an organic acid and an amine having a b.p. 180° C. or more. The fluid has high withstand voltage and can provide repairing effect for the oxide film of the anode foil of the non-solid aluminum electrolytic capacitor. The hybrid aluminum electrolytic capacitor impregnated with the film repairing fluid of the invention has the characteristics of high voltage, high capacity, low impedance and small leakage current, so that the electrolytic capacitor can maintain low equivalent series resistance and low impedance in the high frequency range.
