Ohmite WFH Aluminum Housed Wirewound Power Resistors

Ohmite WFH Aluminum Housed Wirewound Power Resistors utilize Ohmite's flat core winding technology. This technology allows for wire-wound heat sinkable resistors to have a very low profile and superior thermal transfer characteristics when compared to conventional aluminum housed wire-wound resistors. The WFH Aluminum Housed Wirewound Power Resistors offer solder, wire, and "Fast-On" terminations, power ratings from 90W to 330W, a resistance range from 0.22Ω to 39KΩ, and custom wire lengths. No heat sink compound is required because of a large mounting surface.
