Title:
ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2019/194092
Kind Code:
A1
Abstract:
Provided is an electrolytic capacitor having a large capacitance in a high frequency range as a result of increasing the capacitance retention rate. This electrolytic capacitor is used at a frequency range of 100 kHz or higher and has an electrode foil and an electrolyte solution. The capacitance of the electrolytic capacitor at 100 kHz is at least 50% of the capacitance at 120 Hz.
