Single Pulse Graph 000 Pulse Power (W) 00 0 0.000 0.00 0.0 0. Note: The Single pluse graph is the result of 50 rectangular shape pulses that are applied at one-minute intervals. The limit of acceptance was a shift in resistance of less than % from the initial value. The power applied was subjected to the restrictions of the maximum permissible pulse voltage. Multi Pulse Graph 000 Pulse Power (W) 00 0 0.000 0.00 0.0 0. Note: The continuous load graph was obtained by applying repetitive rectangular pulses where the pulse period was adjusted so that the average power dissipated in the resistor was equal to its rated power at 70 C. Again the limit of acceptance was a shift in resistance of less than % from the initial value. Email: sales@venkel.com Phone: 52.794.008 Toll Free: 800.950.8365 Web: www.venkel.com Rev. 03/208 - A 3
