Determine the stability of a typical resistor for
operation under the following pulse-load conditions.
C
A 100 X resistor is required to operate under the
following conditions:
Therefore:
As the operating conditions P ˆ = 1 W and
are lower than these limiting values, this resistor
may be safely used.
S
A 10 k X resistor is required to operate under the
following conditions:
Therefore:
