Pulse Performance
The graphs below show the value changes resulting from applying multiple pulses of increasing peak voltage. The pulse shape
was 1.2/50µS as defined in IEC 6100-4-5 / ANSI C62.41. The highest voltage plotted on each graph represents the maximum
peak voltage for that resistance value.
