Allowable temperature of capacitor

The allowable temperature rise of a capacitor due to power dissipation is determined by experience. For example, this value is + 20 C maximum for molded chip capacitors. This in turn limits the power that the capacitor can dissipate. EQUIVALENT SERIES ...

Choosing a capacitor? Ripple current capability matters as much …

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.
