5Ω 10W Wirewound Resistor ±1% ±50ppm/℃ Chassis Mount Resistors
Mfr. Part #
810F5R0
Model Number
810F5R0
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 are built to withstand vibration, shock, and harsh environmental conditions. The metal housing facilitates chassis mounting, providing effective heat-sinking capabilities for high stability during operation. Non-inductive versions are available.
