Electrolyte for an aluminium-electrolyte capacitor, capacitor which uses the electrolyte and the use of said capacitor

摘要

The invention concerns an operating electrolyte for an electrolytic capacitor that also includes, in addition to ethylene glycol, 1 to 10 weight percent of a derivatized aromatic carboxylic acid. The invention also concerns an aluminum electrolytic capacitor with the operating electrolyte according to the invention. In addition, the invention concerns the use of the capacitor according to the invention. The operating electrolyte according to the invention is distinguished by an improved sparking voltage and permits the capacitor according to the invention to be used at voltages up to 530 V.
