Product Description
Vishay Dale Wirewound Resistors, Industrial Power, Aluminum Housed, Chassis Mount
These industrial power, aluminum-housed wirewound resistors are designed for chassis mounting, utilizing the heat-sink effect for efficient thermal management. Featuring molded construction for total environmental protection and complete welded construction, they offer excellent stability in operation with less than 1% change in resistance. Available in non-inductive styles (type NH) with Ayrton-Perry winding for lowest reactive components, these resistors are suitable for demanding industrial applications.
