Thermistor Assorted Kit 3-Values 9-Pieces

A thermistor is a type of resistor whose resistance varies significantly with temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor.

An NTC thermistor, short for Negative Temperature Coefficient thermistor, is a type of temperature sensor that exhibits a decrease in resistance as the temperature increases. It is made from a semiconducting material with a negative temperature coefficient of resistance.

Here are some key points about NTC thermistors:

1. Temperature Sensitivity: NTC thermistors are highly sensitive to temperature changes. As the temperature rises, the resistance of an NTC thermistor decreases exponentially. The rate of resistance change is determined by the thermistor's temperature coefficient, which is typically specified by the manufacturer.

2. Material and Construction: NTC thermistors are usually made from metal oxides, such as manganese, nickel, or copper oxides. The thermistor is formed into a small bead, disk, or cylindrical shape, and the leads are attached for easy integration into electronic circuits.

3. Resistance and Temperature Relationship: NTC thermistors are characterized by their resistance at a specific reference temperature, typically 25 degrees Celsius (25°C). The resistance decreases as the temperature rises above the reference temperature and increases as the temperature falls below it.

4. Applications: NTC thermistors are widely used in various temperature sensing and control applications, including:

   - Temperature measurement: NTC thermistors can accurately measure temperature and are commonly used in thermostats, temperature monitoring systems, and industrial control applications.
   - Temperature compensation: They are used to compensate for temperature effects on other components or circuits, such as in temperature-compensated crystal oscillators (TCXOs) or temperature compensation networks.
   - Overheating protection: NTC thermistors can be used to detect overheating conditions in electronic devices or equipment and trigger protective measures or shutdown mechanisms.
   - Temperature control: NTC thermistors are used in temperature control systems to maintain a specific temperature or control heating elements.
   - Environmental monitoring: They can be utilized in environmental monitoring systems to measure temperature changes in air, water, or soil.

5. Steinhart-Hart Equation: The resistance-temperature relationship of an NTC thermistor can be described using the Steinhart-Hart equation or other mathematical models that provide a more accurate representation of the non-linear behavior of the thermistor.

6. Calibration and Accuracy: NTC thermistors may require calibration to ensure accurate temperature measurements. Calibration involves comparing the thermistor's resistance values at different temperatures against known temperature references.

It's essential to refer to the datasheets or specifications provided by the thermistor manufacturer for detailed information on the specific characteristics, temperature range, accuracy, and electrical parameters of a particular NTC thermistor.
