To know how long a capacitor will last, the maximum temperature needs to be calculated. Cornell Dubilier’s Expected Life Calculator does this and more. It provides the ability to predict the expected life of a capacitor with operating conditions and the temperature rise of Cornell Dubilier’s screw terminal, snap-in and plug-in capacitors. The calculator is accurate because it is based on extensive thermal measurements of capacitor materials and life tests. Plug-in capacitors are a variation of screw terminal capacitors with tops that features three plug-in copper pins instead of screw terminals.
