HS10033RF

HS/HSN Series Aluminum Housed Axial Terminal Wirewound, Industrial/Commercial Grade F e at u r e s • Standard winding (Model HS) • Non-inductive winding (Model HSN) • Molded construction for total environmental protection • Complete welded construction • Mounts on chassis to utilize heat-sink effect • High stability at conventional power ratings • Flat marking surface for easy identification • RoHS compliant; add “E” suffix to part number to specify. The HS/HSN Series offers greater power capacity (100 and 250 watts) in the same design format as Ohmite’s 89 Series. HS/HSN Series maintains the same construction, materials, and manufacturing techniques as the 89 Series. As a made-to-order product, it is recommended for higher volume applications.
