The resistor is considered to be operating under
single pulse conditions if, during its life, it is loaded
with a limited number (approximately 1,500) of
pulses over long time intervals (greater than one
hour).
R
The resistor is operating under repetitive pulse
conditions if it is loaded by a continuous train of
pulses of similar power.
The dashed line in Fig. 12 shows the observed
maximum load for the Size 1206 chip resistors under
single-pulse loading.
More usually, the resistor must withstand a
continuous train of pulses of repetition time ‘t
during which only a small resistance change is
acceptable. This resistance change (∆R/R) is equal to
the change permissible under continuous load
conditions. The continuous pulse train and small
permissible resistance change reduces the maximum
handling capability.
The continuous pulse train maximum handling
capacity of chip resistors has been determined
experimentally.
Measurements have shown that the handling capacity
varies with the resistive value applied.
However, maximum peak pulse voltages as indicated
in Fig. 13, should not be exceeded.
