These molded-construction metal-housed resistors are available in higher power rat- ings than standard axial resis- tors and are better suited to withstanding vibration, shock and harsh environmental con- ditions. 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 capabili- ties. F E A T U R E S • High Stability: ±0.5% ΔR. • High power to size ratio. • Metal housing allows chassis mounting and provides heat sink capability. 89 Series Metal-Mite® Aluminum Housed Axial Term.
