S T A N D A R D P A R T N U M B E R S The 89 Series is a high-per- formance axial type resistor. 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.
