| titleOfInvention | Electrolytic capacitor |
| abstract | A long-life electrolytic capacitor having low impedance characteristics and having little change in characteristics such as capacitance even after 10000 hours in a load test at a high temperature of 105 ° C. is provided. A capacitor element is formed by winding an anode made of a valve metal having an oxide film on a surface thereof and a cathode made of a valve metal through a separator, and the capacitor element is impregnated with an electrolytic solution, and a sealed case The electrolytic capacitor is configured by being housed inside. The electrolytic solution is obtained by dissolving a salt of azelaic acid and a secondary amine having a hydrophobic substituent in a solvent containing water and ethylene glycol, and the content of the salt is 14 to 14 of the entire electrolytic solution. The range is 22% by mass. The electrolyte contains a large amount of azelaic acid salt, which has a great effect of suppressing electrode deterioration, and secondary amines adsorb to the anode surface to form a hydrophobic layer, which makes it difficult for electrode hydration to deteriorate and high-temperature life characteristics. A good capacitor can be obtained. [Selection figure] None |
