RESISTORS, FIXED, WIRE-WOUND (POWER TYPE, CHASSIS MOUNTED), GENERAL SPECIFICATION FOR
Organization:
DLA - CC - DLA Land and Maritime
Year: 2010
Abstract: 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 capable for application when the alternating current (ac) characteristics are of critical importance; however, provisions have been made to minimize the inductance.Intended Use: The resistors covered by this specification are military unique due to the fact that these devices must be able to operate satisfactorily in military systems under the following demanding conditions: 20 G's of high frequency vibration, 100 G's of shock (specified pulse), thermal shock (with no more than 1 percent deviation in initial resistance), and a low temperature coefficient of resistance. In addition, these military requirements are verified under a qualification system. Commercial components are not designed to withstand these military environmental conditions.
