RESISTOR, VARIABLE, WIREWOUND, NONPRECISION GENERAL SPECIFICATION FOR
Organization:
DLA - CC - DLA Land and Maritime
Year: 2013
Abstract: This specification covers the general requirements for multiturn, lead-screw actuated and single turn wirewound, 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 percentIntended Use: The resistors covered by this specification are military unique due to the fact that these devices must be able to operate satisfactorily in military systems under the following demanding conditions: 15 g's of high frequency vibration, 50 g's of shock (specified pulse), 50 g's of acceleration and resistant to salt corrosion. In addition, these military requirements are verified under a qualification system. Commercial components are not designed to withstand these military environmental conditions.
