Scope.

This specification covers the general requirements for power type, wirewound, 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/OC to 200 ppm/OC 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... View More
