Ohmite's Brown Devil(R) 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.

Material Coating: lead free vitreous enamel. Core: Ceramic. Terminals: Tinned axial; RoHS solder composition is 96% Sn, 3.5% Ag, 0.5% Cu Derating: Linearly from 100% @ +25C to 0% @ +350C. Electrical Tolerance: 1+: 5% under 1: 10% Power rating: Based on 25C free air rating. Overload: 10 times rated wattage for 5 seconds. Temperature coefficient: 5 and under: 400 ppm/C Above 5: 260 ppm/C To calculate max. amps: use the formula P/R.
