General life span of electrolytic capacitors in years
Generally, most capacitors on the market, such as electrolytic capacitors rated at a maximum temperature of 85℃ have a life span of 1000 hours at an ambient temperature of 85℃, while when the ambient temperature is lowered to 60℃, the life span can be extended to about 10000℃, and when the ambient temperature is lowered to 40℃, the life span can be about 80000 hours.

Factors affecting the life of electrolytic capacitors
1The service life of electrolytic capacitor is not only related to the ambient temperature, but also related to the size of ripple current.
2Since thermal stress has a decisive influence on the service life of electrolytic capacitors, thermal loss generated by ripple current is an important factor affecting the service life of electrolytic capacitors.
3 Ripple current is the AC component current flowing through the electrolytic capacitor, which is affected by the ambient temperature and AC frequency, and the maximum allowable value of ripple current is different for different ambient temperatures. And when the ambient temperature is certain, the higher the ripple current flows within the allowed range, the shorter the service life of electrolytic capacitor.
