scope:
This specification covers the general requirements for precision, nonwire-wound, variable resistors whose electrical output (in terms of percent of applied voltage) are linear or nonlinear with respect to the angular position of the operating shaft. This specification includes requirements for linear and nonlinear, single turn and multiturn, single-section (cup) and multi-section variable resistors. These resistors have a resistance tolerance of ±10 percent. These resistors are capable of full-load operation at maximum ambient temperatures of 70°C and are suitable for continuous operation, when properly derated, to maximum temperatures of 125°C, (see 3.1, 6.2, and figure 10). This specification includes procedures and requirements for the acquisition of category I, category II, and category III precision resistors.
intended 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... View More
