PERFOMANCE SPECIFICATION
RESISTORS, FIXED, WIRE-WOUND
(POWER TYPE, CHASSIS MOUNTED),
GENERAL SPECIFICATION FOR
This specification is approved for use by all Department
and Agencies of the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers the general requirements for power type, wire wound, fixed
resistors which utilize the principal of heat dissipation through a metal mounting surface. The resistors
have an initial resistance tolerance of ±1 percent and a resistance temperature characteristic range from
30 ppm/°C to 200 ppm/°C depending upon the resistance value. They are not suitable for application
when the alternating current (ac) characteristics are of critical importance; however, provisions have been
made to minimize the inductance.
1.2 Classification.
1.2.1 Part or Identifying Number (PIN). The PIN is in the following form.
RE65 G 1001
Style
(1.2.1.1)
Characteristic
(1.2.1.2)
Resistance
(1.2.1.3)
1.2.1.1 Style. The style is identified by the two letter symbol “RE” followed by a two digit number; the
letters identify chassis mounted, power type, wire wound, fixed resistor, and the number identifies the size
and power rating of the resistor.
1.2.1.2 Characteristic. The characteristic is identified by a single letter which identifies the maximum
continuous operating temperature, and inductive (G) or noninductive (N) method of winding in accordance
with table I.
