Ohmite's Brown Devils(R) are small, exceptionally durable power resistors. They feature all-welded construction and rugged, flame resistant conformal lead free vitreous enamel coating to ensure successful performance under high temperatures. The wirewound 200 Type resistors have 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 lead mounting option. * Higher power ratings. * Flame-resistant lead free vitreous enamel coating. * RoHS compliant product available Jan. 2006 Add "E" suffix to part number to specify. 200 Series SPECIFICATIONS Material Coating: lead free vitreous enamel. Core: Ceramic. Terminals: Tinned axial lead. Derating: Linearly from 100% @ +25C to 0% @ +350C. Electrical Tolerance: 1 and over: 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.
