MIL-PRF-18546
Resistors, Fixed, Wire-Wound (Power Type, Chassis Mounted), General Specification For (w/Amendment 3)
FSC: 5905
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 per °C to 200 ppm per °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.
