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. 200 Series Spec i f i c a t i on s 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% @ +25°C to 0% @ +350°C. Electrical Tolerance: 1Ω+: ±5% under 1Ω: ±10% Power rating: Based on 25°C free air rating. Overload: 10 times rated wattage for 5 seconds. Temperature coefficient: 5Ω and under: ±400 ppm/°C Above 5Ω: ±260 ppm/°C To calculate max. amps: use the formula √P/R.
