Kegunaan NTC Thermistor – An Introduction
Article Summary
Introduction
NTC (Negative Temperature Coefficient) thermistors are temperature-sensitive resistors that exhibit a decrease in resistance with an increase in temperature. These tiny but powerful devices have a wide range of applications in various industries.
Applications of NTC Thermistors
1. Temperature Measurement and Control: NTC thermistors are commonly used in thermostats, industrial heating systems, and HVAC systems for temperature sensing, regulation, and control.
2. Overheat Protection: They can be used as thermal safety controls in appliances, such as power supplies, battery packs, and electric motors, to prevent overheating and potential damage.
3. Inrush Current Limiting: NTC thermistors act as inrush current limiters in power supplies and electronic devices, preventing excessive current flow during startup.
4. Temperature Compensation: Due to their temperature-sensitive properties, NTC thermistors are utilized in electronic circuits and sensors to provide temperature compensation and stability.
Advantages of NTC Thermistors
1. High Sensitivity: NTC thermistors offer high sensitivity to temperature changes, making them ideal for precise temperature measurements and controls.
2. Small Size: These thermistors are available in compact sizes, enabling their integration into various devices with limited space.
