Organization: NPFC
Publication Date: 15 March 2017
Status: active
Page Count: 22
scope:

This specification covers the general requirements for power type variable resistors having a resistance element of wire, wound linear on an insulating strip shaped in an arc, such that a contact bears uniformly on the resistance element when adjusted by a control shaft. The power ratings (see 3.1) cover a range from 6.25 watts to 1,000 watts, inclusive (see 6.2).

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
