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® 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. SPECIFICATIONS Material Housing: Metal, anodized aluminum. Internal Coating: Silicone. Core: Ceramic. Terminals: Solder-coated axial. Derating: Linearly from 100% @ +25°C to 0% @ +275°C. Metal-Mite® Aluminum Housed Axial Term. Wirewound, 1% Tolerance F A E H B } R N D P terminal hole dia. L M 89 Series Electrical FEATURES • High Stability: ±0.5% ΔR. • High power to size ratio. • Metal housing allows chassis mounting and provides heat sink capability. As of September 2006, the 89 Series is no longer offered as Mil. Spec. 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 1Ω: ±90 ppm/°C 1 to 9.99Ω: ±50 ppm/°C 10Ω and over: ±20 ppm/°C. Dielectric withstanding voltage: 5W and 10W rating,1000 VAC; 25 and 50W ratings, 2250 VAC. G K mount hole dia.
