zBefore 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.
