If it is assumed that Ea of 1.0 for a component is designed to run at 85°C, then the user can calculate the effect (1/AR) on the projected life of the component. The table on this slide shows clearly that minimizing temperature rise is the most direct way to increase reliability. Avoiding temperature cycling is also important, all of which calls for carefully planned thermal management via one or more of the cooling modes: convection, conduction, and radiation.
