Polymer Capacitor

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.

Voltage derating also increases the life of a capacitor, but to a far lesser extent, as compared to temperature deratings. Internal heating, caused by the applied ripple current, reduces the projected life of an aluminum electrolytic capacitor.



L2 = L1 * 10z


L2 = Expected capacitor life in the application
L1 = Guaranteed capacitor life (in hours) at temperature Tm
z = (Tm - Ta) / 20

Load Life rating (L1) : (hours)
Max Temperature (Tm) : (° C)
Ambient Temperature (Ta) : (° C)
