AMBIENT TEMPERATURE DERATING
Derating is required for ambient temperatures above 25°C, see the following graph.
Curves A, B, C apply to operation of unmounted resistors. Curve D applies to all types when mounted to specified heat sink.
A = RH-5 and RH-10 size resistor, unmounted
B = RH-25 size resistor, unmounted
C = RH-50, RH-100 and RH-250 size resistor, unmounted

APPLICABLE MIL SPECIFICATIONS
Date Code
NH NON-INDUCTIVE
MIL-PRF-18546 is the military specification covering
aluminum housed, chassis mount, power resistors. VISHAY
RH and NH resistors are listed as qualified on the
MIL-PRF-18546 QPL.
Models of equivalent physical and electrical specifications are
available with non-inductive (Aryton-Perry) winding. They are
identified by substituting the letter N for R in the model
number (NH-5, for example).
