PERFORMANCE SPECIFICATION
RESISTOR, VARIABLE, NONWIRE WOUND,
(ADJUSTMENT TYPE)
GENERAL SPECIFICATION FOR
This specification is approved for use by all Departments
and Agencies of the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers the general requirements for multiturn lead screw actuated and
single turn nonwire wound, variable resistors with a contact bearing uniformly over the entire surface of
the entire resistive element, when positioned by the actuator. These resistors are capable of full load
operation (where maximum resistance is engaged) at a maximum ambient temperature of 70°C and
85°C, and are suitable for continuous operation when properly derated, at a maximum temperature of
125°C and 150°C (see figure 1). These resistors have a resistance of ±10 percent (see 3.1).
1.2 Classification.
1.2.1 Part or Identifying Number (PIN). The PIN is in the following format, and as specified (see 3.1
and 6.2).
RJ24 F Y 103

Resistance
(1.2.1.4)
1.2.1.1 Style. The style is identified by two letter symbol “RJ” followed by a two-digit number. The
letters identify adjustment type, nonwire wound, variable resistors and the number identifies the physical
size.
