Product Description
Product Overview
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 capable of withstanding vibration, shock, and harsh environmental conditions. The metal housing facilitates chassis mounting, acting as a heat sink to maintain high stability during operation.
