The 89 Series Metal-Mite is a high-performance, aluminum-housed axial terminal wirewound resistor designed for demanding applications. These resistors offer a high power-to-size ratio, excellent stability (0.5% R), and robust construction to withstand vibration, shock, and harsh environmental conditions. The metal housing facilitates chassis mounting and provides effective heat-sinking capabilities, ensuring high stability during operation. Non-inductive versions are available for specialized needs.
