RESISTOR, VARIABLE, NONWIREWOUND (ADJUSTMENT TYPE), NONESTABLISHED RELIABILITY, AND ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR

Organization:

DLA - CC - DLA Land and Maritime

Year: 2011

Abstract: This specification covers the general requirements for nonestablished reliability (non-ER) and established reliability (ER), multiturn lead-screw actuated, and single-turn, nonwirewound, variable resistors with a contact bearing uniformly over the surface of the entire resistive element, when positioned by an actuator. These resistors are capable of full-load operation (when the maximum resistance is engaged), at a maximum temperature of 150OC, with a resistance tolerance of ±10 percent. The ER resistors will have life failure rate levels ranging from 1.0 to 0.001 percent per 1,000 hours (see 1.2.1.5). These failure rate levels are established at a 60 percent confidence level maintained at 10 percent producer's risk on the basis of the life tests.Intended Use: Resistors covered by this specification are intended for use in electronic equipment, and are used for matching, balancing, adjusting circuit variables in computers, telemetering equipment, and other critical applications. Resistors covered by this specification are unique due to the fact that these devices must be able to operate satisfactorily in military systems under the following demanding conditions: 20Gs of high frequency vibration, 100 Gs of shock (specified pulse), undergo moisture resistance, setability and salt corrosion test. In addition these military requirements are verified under a qualification system. Commercial components are not designed to withstand these military environmental conditions.
