Resistor, Variable, Wirewound (Low Operating Temperature), General Specification for w/Amendment 3 FSC: 5905

This specification covers the general requirements for variable resistors having a resistance element of wire, wound on an insulating strip shaped in an arc, so that a contact 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 +40°C and are suitable for continuous operation when properly derated, at a maximum temperature of +105°C.
