Rated voltage
The voltage rating is calculated by the following equation. If the value
obtained exceeds the limiting element voltage, the voltage rating is
equal to the maximum operating voltage.

•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.
