This specification covers the general requirements for multiturn, lead-screw actuated and single turn
wire wound, variable resistors with a contact bearing uniformly over the entire surface of the entire resistive element,
wound linearly, when positioned by an actuator. These resistors are capable of full load operation (where maximum
resistance is engaged) at maximum ambient temperature of 85oC, and are capable for continuous operation when
properly derated, at a maximum temperature of 150oC (see figure 2). These resistors have a resistance tolerance of
±5 percent (see 3.1).
