If the I2R effects exceed the capacitor''s ability to dissipate heat, its temperature can rise and hence adversely affect reliability. At the least, the component lifetime may be affected according to the Arrhenius Law, which states that lifetime is reduced by half for every 10°C increase in operating temperature.

Specifications Most run capacitor applications use a rating of 2.5-100 uf (microfarads) capacitance and voltages of 370 or 440 VAC. They are also usually always 50 and 60 Hz rated. Case designs are round or oval, most commonly using either a steel or aluminum ...
Where ΔT is temperature rise in ºC. DF of a capacitor is frequency and temperature dependent and Life Expectancy is usually specifed at 25 ºC and 1 kHz. The life expectancy formula for the power flm capacitors in this catalog* is given in terms of appliedESR
temperature rise due to the ripple current heating: 2 ∆= × ×TI ESRRrms th [3] The higher the ripple current, ESR, and thermal resistance between the capacitor and ambient the higher the temperature rise of the capacitor. The temperature of the capacitor is di
The higher the long-term temperature of the electrolytic capacitors, the shorter the life of the component. It is strongly recommended to keep its temperature 5°C – 10°C below …
Each capacitor is designed for a particular rated voltage, which it must stand up to without adverse effect during continuous operation. However, this only applies to ambient temperatures of < +85 C; at higher temperatures the maximum permissible voltage or voltage limit for continuous operation is reduced by voltage derating. ...
