Single Pulse

The single impulse graph is the

result of 50 impulses of rectangular

shape applied at one-minute

intervals. The limit of acceptance

was a shift in resistance of less

than 1% from the initial value.

Continuous Load Due

to Repetitive Pulses

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

1% from the initial value.
