89 Series Metal-Mite(R) Aluminum Housed Axial Terminal Wirewound, 1% Tolerance The 89 Series is a high-performance axial type resistor. These molded-construction metal-housed resistors are available in higher power ratings than standard axial resistors and are better suited to withstanding vibration, shock and harsh environmental conditions. The 89 Series Metal-Mite(R) resistors are aluminum housed to maintain high stability during operation and to permit secure mounting to chassis surfaces. The metal housing also provides heat-sinking capabilities. F e at u r e s * High Stability: 0.5% R * High power to size ratio * Metal housing allows chassis mounting and provides heat sink capability S e r i e s s p e c i f i c at i o n s Series 805 810 825 850 Wattage 5 10 25 50 Ohms 0.10-25K 0.10-50K 0.010-75K 0.005-100K Voltage 210 320 520 1170 Non-Inductive versions available. Insert "N" before tolerance code. Example: 850NF560 Characteristics Housing Metal, anodized aluminum Internal Coating Silicone Core Ceramic Terminals Solder-coated axial Derating Linearly from 100% @ +25C to 0% @ +275C. Tolerance 1% and 5% (other tolerances available). Power rating Rating is based on chassis mounting area and temperature stability. Proper heat sink as follows: 5W and 10W units, 4" x 6" x 2" x .040" Aluminum chassis; 25W units, 5" x 7" x 2" x .040" Aluminum chassis; 50W units, 12" x 12" x .059" Aluminum panel. Maximum ohmic values See chart. Overload 5 times rated wattage for 5 seconds. Temperature coefficient Under 1: 90 ppm/C; 1 to 9.99: 50 ppm/C; 10 and over: 20 ppm/C. Dielectric withstanding voltage 5W and 10W rating,1000 VAC; 25 and 50W ratings, 2250 VAC.
