Plot Your Derating Guidelines
The concept of derating is similar to the mechanical engineering concept of a stress–strength analysis.
The intent is to ensure that the selected component or the mechanical design has sufficient strength to withstand the expected applied stresses.
Components operating at or near their rated values have short lives. Consequently, the general practice is to use components for materials well below their rated values to extend the operating life of the items.
This is where derating comes into play. [Read more…]
