Brown Devil® Vitreous Enamel Power
Ohmite’s Brown Devil® is a small, exceptionally
durable power resistor. It features all-welded con-
struction and rugged, flame resistant conformal lead
free vitreous enamel coating to ensure successful
performance under high temperatures.
The wirewound 200 Series has a hollow-core con-
struction, which accommodates rigid mounting with
brackets or thru bolts.
Mounting brackets not included with resistors.
