Manganin 290 Polyimide Manganin® Insulated Wire is a wire from Goodfellow's range of wires. With a resistance temperature coefficient of just 2ppm/°C, this wire has very low resistivity drift with temperature. The polyimide insulation allows operation up to 290°C. Applications include precision resistors, thermocouples, and instrumentation wiring where stability and high temperature performance are critical. This wire is ideal for miniaturized circuits or high density wiring harnesses.
