200 Series

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.

F e at u r e S
