ELECTROLYTIC CAPACITOR ELECTROLYTE AND ELECTROLYTIC CAPACITOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an aluminum electrolytic capacitor which has satisfactory high-temperature life characteristic, and further satisfactory low-temperature characteristic. SOLUTION: Mixed solvent of sulfolane and 1,3-dimethyl-3,4,5,6 tetrahydro-2(1 H)-pyrimidinone is used as the electrolyte for an electrolytic capacitor. The electrolytic capacitor using the electrolyte has satisfactory high temperature life characteristic, and further satisfactory low-temperature characteristic.
