Ohmite 89 Metal-Mite® Axial Terminal Wirewound Resistors

Ohmite 89 Metal-Mite® Axial Terminal Wirewound Resistors are high-performance, axial type resistors available in higher power ratings than standard axial resistors that are better suited to withstanding vibration, shock, and harsh environments. The 89 Metal-Mite® Resistors from Ohmite have a molded construction and metal housing that provides heatsink capability. These resistors are also aluminum housed to maintain high stability during operation and to permit secure mounting to chassis surfaces.

Features

  • High stability of ±0.5% ΔR
  • High power to size ratio
  • Power rating of 5W to 50W with proper heatsink
  • RoHS compliant
  • Resistance range of 0.005Ω to 100KΩ
  • Metal housing allows chassis mounting and provides heat sink capability
  • Tolerances of ±1% and ±5% (other tolerances available)
  • Non-inductive versions available
