More usually, the resistor must withstand a
continuous train of pulses of repetition time ‘t p ’
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.
