Patent ID: 11177080

Abstract:
A conductive polymer hybrid aluminum electrolytic capacitor having a high withstand voltage with a rated voltage of 63 V or higher, high heat resistance to high temperature reflow solder, and durability and reliability under high temperature environment with 125° C. or higher is provided. In a conductive polymer hybrid aluminum electrolytic capacitor having an electrolytic solution and a cathode with conductive polymer, the electrolytic solution contains a solute and a solvent, the solvent contains diethylene glycol and/or triethylene glycol as a main component, the solute contains a long-chain dibasic carboxylic acid with 12 or more carbon atoms and an amine with a high boiling point, and the electrolytic solution is contained in a space of the capacitor element to which a solid electrolytic layer by conductive polymer is formed.
