Standard part numberS for 200 SerieS

200 Series

Ohmite’s Brown Devil® is a small, exceptionally durable power resistor. It features all-welded construction and rugged, flame resistant confor- mal lead free vitreous enamel coating to ensure successful performance under high tem- peratures. The wirewound 200 Series has a hollow-core construc- tion, which accommodates rigid mounting with brackets or thru bolts. Mounting brackets not included with resistors.
