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.
