Vishay Dale RER wirewound resistors feature an aluminum heat sink housing in a molded construction for total environmental protection. These resistors are available in non-inductive styles (type ENH) with Ayrton-Perry winding for lowest reactive components, and are qualified to MIL-PRF-39009. The resistors can be mounted on chassis to utilize heat-sink effect.
