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

• Rugged lead free vitreous enamel coating

• All-welded construction.

• Self supporting terminal mounting option.

• Higher power ratings.

• Flame-resistant lead free vitreous enamel coating.

• RoHS compliant product available. Add “E” suffix to

part number to specify.
