Projected Life at Operating Conditions (L2)


The operating conditions directly affect the life of an aluminum electrolytic capacitor. The ambient temperature has the largest effect on life. The relationship between life and temperature follows a chemical reaction formula called Arrhenius' Law of Chemical Activity. The capacitor’s life doubles for every 10 degree Celsius decrease in temperature.
