An electrolytic capacitor having a wound foil capacitor section, preferably aluminum foil, contains as electrolyte a solution of 3 to 10 wt % ammonium benzoate, 4 to 16 wt % water, and 75 to 93 wt % ethylene glycol which has a resistivity of 385 to 620 ohm-cm and provides a capacitor capable of operating above 100 V and above 85 DEG C. A nitro compound and a phosphate may also be present. The electrolyte is particularly suited for operation above 200 V and 95 DEG C. and higher.
