How to calculate the lifetime of a capacitor?

The heating of the ripple current flowing in the capacitor must be measured and must not exceed 5°C. The surface temperature should be reduced according to the heating generated by the ripple current. To calculate the lifetime is the determination of ΔTA - core temperature rise due to the application current in the ca-pacitor - necessary. a.

How does temperature affect the life of an electrolytic capacitor?

Life is doubled when the temperature of the electrolytic is reduced by 10°C. In most applications, such as switch mode power supplies or converters, however, the electrolytic capacitors are con-stantly charged and discharged, which, due to the ohmic losses, results in a not insignificant increase in the temper-ature of the component.
