Overload Duration in Seconds
The energy absorbed by the resistor expressed in Joules can be
calculated by multiplying the peak power of the pulse in watts
times the length of the pulse in seconds.
The energy should not exceed the limits shown in the graph.
The overload voltage should not exceed 1.5 times the maximum
operating voltage.
