When you need the highest quality wirewound axial lead resistors available, choose Ohmite's 90 Series resistors. They are manufactured by a unique process that molds the vitreous enamel over the resistive element, helping to ensure consistent dimensions. This uniformity permits 90 Series resistors to be mounted in clips, creating a heat-sinking benefit (see next page). The durable vitreous enamel coating, which is totally lead free, permits the 90 Series resistors to maintain a hard coating while operating at high temperatures. Mechanical integrity is enhanced by the all-welded construction. FEATURES * Molded Construction provides consistent shape and size (Permits mounting in clips which extends power rating). * Meets MIL-R-26 requirements for insulated resistors. * All-welded construction. * Flame resistant lead free vitreous enamel coating. * Higher ratings in smaller sizes. * Heat sink mounting clips available. SPECIFICATIONS Material Coating: Molded lead free vitreous enamel. Core: Ceramic. Terminals: Solder-coated copper clad axial lead. Derating: Linearly from 100% @ +25C to 0% @ +350C. Electrical Tolerance: 5% (other tolerances available). Power rating: Based on 25C free air rating. (other wattages available*). Maximum ohmic values: See chart. Overload: Under 11 watts: 5 times rated wattage for 5 seconds. 11 watts: 10 times rated wattage for 5 seconds. Temperature coefficient: 1 to 9.99: 100 ppm/C 10 and over: 30 ppm/C Dielectric withstanding voltage: 500 VAC: 1 watt rating 1000 VAC: 2, 3, 5 and 11 watt rating. 90 Series Lead Free Vitreous Enamel Molded Axial Lead Wirewound Resistors 5% Tolerance Standard 1.5 / 38.1 L Series Wattage* Ohms 91 1.5 0.1-3.6K 92 2.25 0.1-3.5K 93 3.25 0.1-10.5K 95 5.0 0.1-25K 90 11.0 0.1-91K D Dimensions (in. / mm) Length Diam.
