What is a NTC thermistor?

An NTC thermistor (Negative Temperature Coefficient Thermistor) is a temperature sensor that decreases in resistance as the temperature increases. It is widely used for temperature measurement and temperature control applications. NTC thermistors are highly sensitive to temperature changes and provide accurate measurements, making them common in electrical devices and home appliances. The resistance of an NTC thermistor decreases rapidly as the temperature rises, allowing the sensor to detect temperature variations. Based on the resistance changes, the temperature can be monitored. Due to its small size and low cost, the NTC thermistor is widely used in various electronic devices.

Application of NTC thermistor

✅ Temperature Control in Household Appliances
NTC thermistors are used in household appliances like refrigerators and microwaves to monitor temperatures, preventing overheating and ensuring efficient operation. As the temperature rises, the resistance decreases, and the control circuit adjusts to maintain the appropriate temperature.
✅ Battery Management Systems
NTC thermistors are used to monitor the temperature of lithium-ion batteries, preventing damage caused by overheating. If the temperature rises excessively, the battery management system issues a warning and helps protect the battery safely.
✅ Automotive Cooling Systems
In automotive engines, NTC thermistors are used to monitor engine temperatures in real-time. If abnormal temperature changes are detected, the cooling fan is activated to maintain the engine at an optimal temperature.
✅ Air Conditioning Systems
In air conditioning units, NTC thermistors are used as temperature sensors to detect room temperatures and enable efficient heating or cooling. If the temperature exceeds a set threshold, the thermistor senses this change and the air conditioning system automatically adjusts accordingly.
