Product Description

Manganin Wire/ Shunt Resistor (6J13, 6J12, 6J8)

Product Description

Manganin wire widely used for low voltage instrumentation with the highest requirements, the resistors should be carefully stabilised and the application temperature should not exceed +60 °C. Exceeding the maximum working temperature in air may result in a resistance drift generated by oxidizing. Thus, the long-term stability can be affected negatively. As a result, the resistivity as well as the temperature coefficient of the electric resistance may slightly change. It is also used as low cost replacement material for silver solder for hard metal mounting.
