89 series Metal-Mite Aluminum Housed Axial Terminal Wirewound, 1% Tolerance The 89 Series is a high-per formance axial type resistor. These molded-construction metal-housed resistors are available in higher power ratings than standard axial resistors and are better suited to with- standing vibration, shock and harsh environmental Features conditions. The 89 Series Metal-Mite resistors are aluminum High Stability: 0.5% R housed to maintain high stability during operation High power to size ratio and to permit secure mounting to chassis sur faces. Metal housing allows chassis mounting and pro- The metal housing also provides heat-sinking vides heat sink capability capabilities. series speCiFiCations Series Wattage Ohms Voltage 805 5 0.10-25K 210 810 10 0.10-50K 320 825 25 0.010-75K 520 850 50 0.005-100K 1170 Non-Inductive versions available.
