Capacitance drops quasi-exponentially in the first few months; then an almost linear section follows over several years of operation. The period of relative stability ends with the abrupt failure of the capacitor at the end of its life.
Aging is distinguished between the following changes in the capacitor performance: Change in capacitance, ESR and leakage current during operation (with voltage applied) and reduction of dielectric strength due to degradation of the dielectric (no voltage applied).
Since the development and production of electrolytic capacitors, designers have had to deal with the issues of aging and shelf life of these products. Electrolytic capacitors have been around for a very long time, but the rapid increase did not occur until the 1960s.
With power density demands increasing and as the only component wear out mechanism in the product, the electrolytic capacitors used in the design determine the service life of the power supply and hence either the service life or the service interval, if the equipment is maintained, of the end application.
