Thermistors – Precision Temperature Sensing and Protection

Introduction

Thermistors are temperature-sensitive resistors widely used for temperature measurement and circuit protection. Their resistance varies significantly with temperature, allowing precise monitoring and control in electronic systems.

Types

• NTC (Negative Temperature Coefficient): Resistance decreases as temperature rises

• PTC (Positive Temperature Coefficient): Resistance increases as temperature rises

Applications

• Overcurrent and overtemperature protection

• Temperature sensing in electronic circuits

• Inrush current limiting during power-up

Advantages

• Accurate temperature measurement

• Protects circuits from thermal damage

• Suitable for a wide variety of industrial and consumer applications

Conclusion

Thermistors are essential for monitoring and controlling temperature, ensuring the safe and reliable operation of electronic devices.
