Alloy resistors are electronic components used in applications such as limiting current, measuring voltage and resistance values. Alloy resistance is an alloy made of mixing two or more metals (such as chromium, nickel and copper, etc.) at a certain proportion, and adjusting the resistance value by adjusting the proportion of different metals in the alloy.

Its main role is to provide a stable resistance value, because its resistance value changes with the temperature of the temperature coefficient is very small, can provide accurate and reliable resistance under various environmental conditions. In addition, alloy resistors also have high temperature retention capabilities and can operate at high temperatures for long periods of time. It can also be used for temperature compensation in circuits to improve the accuracy and reliability of circuits.
