NTC thermistor models and parameters, how to connect NTC thermistors 2

5. Accuracy: The indicator refers to the allowable deviation of the resistance value at temperature, generally ± 1%, ± 2%, ± 3%, etc. diode

6. Thermal time constant: refers to the speed at which an NTC thermistor responds to temperature changes. The smaller the time constant, the faster the response speed.

7. Dissipation coefficient: The power required for an NTC thermistor to increase by 1 ° C in natural convection, usually expressed in mW/° C.

The wiring method of NTC thermistor:

The wiring of NTC thermistor is usually determined according to the requirements and functions of the circuit. Here are several typical wiring methods:

1. Series connection method: NTC thermistor is connected in series with other resistors and can be used for temperature compensation in circuits. diode

2. Parallel connection method: NTC thermistor is connected in parallel with other resistors, which can be used to limit the current of the circuit during temperature changes.

3. Voltage divider connection method: A voltage divider is composed of an NTC thermistor and a fixed resistor, commonly used for simulating temperature sensing.

4. Bridge method: Using NTC thermistor as a part of Wheatstone bridge for precise temperature detection. diode
