Vishay Dale Wirewound Resistors, Industrial Power, Aluminum Housed, Chassis Mount

These industrial power wirewound resistors are designed for chassis mounting, utilizing the heat-sink effect for efficient thermal management. They feature a molded construction for complete environmental protection and welded construction for reliability. Available in both standard (RH) and non-inductive (NH) styles, these resistors are suitable for applications requiring high power dissipation and excellent stability. The non-inductive NH series utilizes an Ayrton-Perry winding for minimal reactive components.
