100K NTC Thermistor Temperature Sensor

A 100K NTC (Negative Temperature Coefficient) thermistor is a type of temperature sensor whose resistance decreases as the temperature increases. The "100K" designation refers to the nominal resistance of the thermistor at a standard temperature, often 25 degrees Celsius.

Nominal Resistance: The nominal resistance of the thermistor at a standard temperature (usually 25°C) is 100,000 ohms or 100 kilohms (K).

Temperature Coefficient: NTC thermistors have a negative temperature coefficient, meaning that their resistance decreases as the temperature rises. The rate at which the resistance changes with temperature is specified by the temperature coefficient (usually given in units of ohms per degree Celsius, ohms/°C).

Application: NTC thermistors are commonly used in temperature-sensing applications. They can be integrated into various devices and systems to monitor and control temperature.

Circuit Connection: In a simple circuit, the NTC thermistor is often connected as one leg of a voltage divider circuit along with a fixed resistor. The voltage across the NTC thermistor changes with temperature, and this change can be measured and converted to a temperature value using appropriate circuitry.

Calibration: Calibration is necessary to correlate the resistance of the thermistor with the actual temperature. This involves measuring the resistance at known temperatures and creating a calibration curve.

Accuracy and Response Time: The accuracy and response time of the sensor depend on factors such as the quality of the thermistor, the circuit design, and the overall system integration.

Applications: NTC thermistor temperature sensors find applications in a wide range of fields, including industrial automation, automotive systems, HVAC (heating, ventilation, and air conditioning), and medical devices.
