Ohmite B5J27RE Brown devil vitreous enamel power Datasheet

Ohmite’s Brown Devil® is a
small, exceptionally durable
power resistor. It features
all-welded construction 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 construction, which accommodates
rigid mounting with brackets or
thru bolts.
Mounting brackets not
included with resistors.
Features
• 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.
