DERATING
P Series Resistors
must be derated for
tolerances below
0.1% and for elevated
ambient temperatures. Choose the
curve corresponding
to the desired tolerance. Determine the
maximum allowed
percentage of rated
power from the graph
based on the maximum
ambient temperature
expected during use.

Ohmite’s P Series Epoxy
molded Precision Wirewound
Resistors are designed to
meet the exacting requirements of Military Specification
MIL-R-93. The P Series offers
high stability and low Temperature Coefficient of Resistance
(TCR). These resistors offer
tolerances as accurate as
±0.005% and Temperature Coefficients of Resistance (TCR)
as low as ±2PPM/°C in a wide
range of resistance values.
