Title:
SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2024/058159
Kind Code:
A1
Abstract:
This solid electrolytic capacitor is provided with: a capacitor element which comprises a positive electrode part and a negative electrode part; a positive electrode lead frame which is connected to the positive electrode part; a negative electrode lead frame which is connected to the negative electrode part; and an insulating sealing material which covers the capacitor element, while partially covering the positive electrode lead frame and the negative electrode lead frame. With respect to this solid electrolytic capacitor, the capacitor element comprises a solid electrolyte; and if 5 g of the sealing material is immersed in 50 cc of water or an aqueous methanol solution that has a pH of 7.0 within a pressure-resistant container, and is subsequently heated at 121°C for 24 hours, the pH value of the water or aqueous methanol solution after the heating is 6.0 to 8.1. Consequently, the present invention is able to provide a solid electrolytic capacitor which is not susceptible to a decrease in the capacitance even if a voltage is applied thereto in a high-temperature high-humidity environment.
