Product Description
Vishay Dale Wirewound Resistors, Industrial Power, Aluminum Housed, Chassis Mount
These industrial power wirewound resistors are designed for chassis mounting, leveraging the heat-sink effect for efficient thermal management. Featuring a 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 both standard (RH) and non-inductive (NH) styles, these resistors meet applicable requirements of MIL-PRF-18546 and are suitable for various industrial power applications.
