Power must be derated according to the power derating curve in

Figure 1 when ambient temperature exceeds 70˚C.

The voltage rating is calculated by the following equation.

•Before using components in circuits where they will be exposed to transients such as pulse loads (short-duration, high-level loads), be certain to evaluate the

component in the mounted state. In addition, the reliability and performance of this component cannot be guaranteed if it is used with a steady state voltage that

is greater than its rated voltage.
