What is the purpose of having a small temperature coefficient of resistance?

The small temperature coefficient of resistance means that the resistance value changes less with temperature, which plays multiple important roles in electronic circuit design:

Improving circuit stability: The resistance value changes less with temperature, which helps to maintain the stability of circuit parameters and reduce performance changes caused by temperature fluctuations
Reducing errors: In precision measurement and signal processing circuits, reducing the temperature coefficient of resistance can reduce measurement errors or signal distortion caused by temperature drift
Extending equipment lifespan: The impact of temperature changes on resistance may lead to material fatigue, and using resistors with low temperature coefficients can help extend equipment lifespan
Reduce maintenance costs: Reduce performance degradation caused by temperature changes, thereby lowering equipment maintenance costs and frequency
Improving overall system performance: In systems that require long-term stable operation, such as communication equipment, medical equipment, etc., using low temperature coefficient resistors can improve the overall performance and reliability of the system
Simplified design: In circuit design, if the temperature coefficient of the resistor is low, the designer may not need to consider complex temperature compensation circuits, thus simplifying the design
Improving energy efficiency: Using low temperature coefficient resistors in power management circuits can help improve the energy efficiency of the power supply
Improving thermal management: Resistors with low temperature coefficients have smaller resistance changes when the temperature changes, which helps to improve the thermal management of the circuit
Enhancing product competitiveness: Using low temperature coefficient resistors can improve the technical specifications and market competitiveness of products
