200 Series
Brown Devil® Vitreous Enamel Power
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.
Mounting brackets not
included with resistors.
F E a tur E s
• Rugged lead free vitreous enam-
el coating
• All-welded construction.
• Self supporting terminal mount-
ing option.
• Higher power ratings.
• Flame-resistant lead free vitre-
ous enamel coating.
• RoHS compliant product avail-
able. Add “E” suffix to part num-
ber to specify.
