    摘要: An electrolytic capacitor particularly adapted for use over a wide temperature range and at a medium to high operating voltage comprising aluminum anode and cathode members separated by an insulating spacer impregnated with an electrolyte consisting essentially of a solution of boric acid and an amine of a molecular weight of not greater than about 175 in a mixture of a member of the group consisting of butyrolactone, dimethylacetamide and dimethylformamide and mixtures of dimethylacetamide and dimethylformamide in a major amount and a polyalkylene glycol of a molecular weight of not greater than about 2000 in a minor amount, said electrolyte being free of α-hydroxocarboxylic acids.
