What is an NTC Thermistor?
NTC (Negative Temperature Coefficient) thermistors are temperature-sensitive resistors that exhibit a decrease in resistance as the temperature increases. This characteristic makes them highly accurate and reliable for temperature sensing in various industrial, automotive, and medical applications.
NTC Thermistor Applications
NTC thermistors are widely used in various industries due to their high sensitivity and precision. Common applications include:
1. Industrial & HVAC Systems
- Used in air conditioning and refrigeration for precise temperature control.
- Employed in heating systems and boilers for thermal regulation.
2. Automotive Industry
- Engine temperature sensors for optimal performance and overheating prevention.
- Battery temperature monitoring in electric vehicles (EVs) and hybrid systems.
3. Medical Equipment
- Used in patient monitoring devices such as thermometers.
- Incorporated into incubators for maintaining stable temperatures.
4. Consumer Electronics
- Temperature regulation in power supplies and lithium-ion batteries.
- Over-temperature protection in circuit boards and electronic devices.
