Title:
SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2024/070287
Kind Code:
A1
Abstract:
Provided is a solid electrolytic capacitor combining low ESR with high withstand voltage. The solid electrolytic capacitor includes a capacitor element comprising an anode foil, a cathode object, and an electrolyte. The anode foil has a surface with an increased area due to tunnel-shaped etching pits and has a dielectric coating film on the surface. The cathode object faces the anode foil. The electrolyte includes a solid electrolyte layer comprising an electroconductive polymer. The weight of the electroconductive polymer is 11 mg/cm3 or less per unit volume of the capacitor element.
