DSC Series
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.

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.
