Ohmite’s P Series Epoxy
molded Precision Wirewound
Resistors are designed to
meet the exacting require-
ments of Military Specification
MIL-R-93. The P Series offers
high stability and low Tempera-
ture Coefficient of Resistance
(TCR). These resistors offer
tolerances as accurate as
±0.005% and Temperature Co-
efficients of Resistance (TCR)
as low as ±2PPM/°C in a wide
range of resistance values.
FEATURES
• Wide Range of Precise
Tolerances (±0.005% to ±1%).
• Low Inductance.
• RoHS Compliant.
• Axial configuration convenient
for PCB and hard wiring applica-
tions.

TCR Matching: to ±0.5 PPM/°C
at 25°C
DERATING
P Series Resistors
must be derated for
tolerances below
0.1% and for elevated
ambient tempera-
tures. Choose the
curve corresponding
to the desired toler-
ance. Determine the
maximum allowed
percentage of rated
power from the graph
based on the maximum
ambient temperature
expected during use.
