MIL-R-39007/7 Revision F, February 20, 1990
RESISTOR, FIXED, WIRE-WOUND (POWER TYPE), ESTABLISHED RELIABILIITY STYLE RWR78
Includes all amendments and changes through Amendment 1, October 4, 1990
Additional Comments: CNCL S/S BY MIL-PRF-39007/7
This specification covers the detail requirements for style RWR78, established reliability, power type, wire-wound, fixed resistor. These resistors are available with terminal types S and W (solderable, inductively wound), and terminal Z (weldable, noninductively wound).
The term Part or Identifying Number (PIN) is equivalent to the term (part number, identification number, and type designator) which was previously used in this specification. Resistors covered by this specification shall be identified by a PIN which shall consist of the style designation, terminal and winding, coded resistive value, tolerance, and failure rate level. The PIN shall be derived in accordance with MIL-R-39007 and shall be in the following form:
