MIL-PRF-39023D (W/ AMENDMENT-1), PERFORMANCE SPECIFICATION: RESISTORS, VARIABLE, NONWIREWOUND, PRECISION, GENERAL SPECIFICATION FOR (21-SEP-2010)

MIL-PRF-39023D (W/ AMENDMENT-1), PERFORMANCE SPECIFICATION: RESISTORS, VARIABLE, NONWIREWOUND, PRECISION, GENERAL SPECIFICATION FOR (21-SEP-2010)., This specification covers the general requirements for precision, nonwirewound, 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 70OC and are capable for continuous operation, when properly derated, to maximum temperatures of 125OC, (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.
