This document describes silicone coated wire wound resistors made by HTR. The resistors come in various power ratings from 10W to 600W, resistance ranges from R22 to 120K, and dimensions depending on power rating. They have flame retardant silicone coating, can operate from -55C to 350C, and are suitable for applications requiring dissipating large amounts of power like voltage dividers and load resistors. Ordering information includes specifying series type, power rating, resistance value, tolerance, and mounting hardware.
