MIL-PRF-22097J, PERFORMANCE SPECIFICATION, RESISTOR, VARIABLE, NONWIREWOUND, (ADJUSTMENT TYPE) GENERAL SPECIFICATION FOR (27 JUL 2007)., This specification covers the general requirements for multiturn lead screw actuated and single turn nonwirewound, variable resistors with a contact bearing uniformly over the entire surface of the entire resistive element, when positioned by the actuator. These resistors are capable of full load operation (where maximum resistance is engaged) at a maximum ambient temperature of 70OC and 85OC, and are capable for continuous operation when properly derated, at a maximum temperature of 125OC and 150OC (see figure 1). These resistors have a resistance of ±10 percent (see 3.1).
