MIL-R-18546F, MILITARY SPECIFICATION: RESISTORS, FIXED, WIRE-WOUND (POWER TYPE, CHASSIS MOUNTED), GENERAL SPECIFICATION FOR (03-MAY-1994)(S/S BY MIL-PRF-18546F]

MIL-R-18546F, MILITARY SPECIFICATION: RESISTORS, FIXED, WIRE-WOUND (POWER TYPE, CHASSIS MOUNTED), GENERAL SPECIFICATION FOR (03-MAY-1994)(S/S BY MIL-PRF-18546F]., 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/Degrees C to 200 ppm/Degrees C depending upon the resistance value. They are not capable for application when the alternating current (ac) characteristics are of critical importance; however, provisions have been made to minimize the inductance.
