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.
