Title:
ELECTROLYTIC CAPACITOR
Document Type and Number:
Japanese Patent JPH11283874
Kind Code:
A
Abstract:

To obtain an electrolytic capacitor with high breakdown voltage, which has superior impedance characteristics, leakage current and reliability.

This electrolytic capacitor has a constitution using a capacitor element 12, which has an anode foil 1 comprising a valve-action metal in which a dielectric surface oxide film is formed on the surface, a cathode foil 3, solid organic conducting material 2 formed between the anode foil 1 and the cathode foil 3 and driving an electrolyte solution 10. Thus, the electrolytic capacitor at the high withstand voltage having the excellent impedance characteristics, leakage current and reliability can be realized.
