MILITARY SPECIFICATION
RESISTOR, FIXED, WIRE WOUND (POWER TYPE),
STYLES RW70, RW74, RW78, and RW79
THIS SPECIFICATION IS INACTIVE FOR NEW DESIGN (SEE 6.4)
This specification is approved for use by all Depart-
ments and Agencies of the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers the associated requirements for styles RW70, RW74, RW78, and
RW79 resistors.
1.2 Part or Identifying Number (PIN). Resistors covered by this specification are identified by a PIN,
which consists of the style designation, characteristic, and coded resistive value. The PIN is derived in
accordance with MIL-PRF-26 and is in the following form:
49R9
