Organization: NPFC
Publication Date: 3 February 2017
Status: active
Page Count: 25
scope:

This specification covers the general requirements for variable resistors having a resistance element of wirewound on an insulating strip shaped in an arc, so that a contract bears uniformly on the resistance element when adjusted by a control shaft. These resistors are capable of full load operation at an ambient temperature of +40OC and are capable of continuous operation when properly derated, at a maximum temperature of +105OC.

 

intended Use:

Resistors covered by this specification are intended for use in electronic equipment, and are used for matching, balancing, and adjusting circuit variables in computers, telemetering equipment,... View More
