Temperature Sensors - NTC Thermistors

The NC20M00273KBA is a type of temperature sensor known as an NTC thermistor. NTC thermistors, or Negative Temperature Coefficient thermistors, are a type of temperature-sensing device commonly used in many industrial and commercial applications. They are composed of small pieces of ceramic material that contain a mixture of semiconductor material which changes resistance as the temperature changes.NTC thermistors are generally considered more accurate than the other types of thermistors as they have a smaller range of temperature that they will sense, and the resistance change also tends to be more linear. This makes them an ideal choice for applications where precise temperature reading is necessary.The NC20M00273KBA is an example of an NTC thermistor. It is a 10 kΩ NTC thermistor with a 3950 ± 1% B value and a temperature range of -20°C to +120°C. It has a negative temperature coefficient (NTC) of -3.9%/°C from 25°C to 125°C. This means that as the temperature increases, the resistance decreases proportionally. It is a 3-terminal device with an internal lead frame which helps with heat transfer and provides a mechanical connection between the device and PCB.In terms of applications, the NC20M00273KBA is typically used in conjunction with a pull-up resistor to form a voltage divider circuit, allowing the output to be read by a microcontroller or other device. The thermistor is one end of the voltage divider with the pull-up resistor on the other. As the temperature changes, the resistance of the NTC thermistor also changes, resulting in a corresponding change in the voltage output of the circuit. This allows the temperature to be measured accurately.The NC20M00273KBA is also commonly used as an over-temperature alarm. When the ambient temperature reaches a certain limit, the resistance of the thermistor changes drastically which causes a corresponding change in the output voltage. This change in voltage can then be detected by a microcontroller and used to activate a warning alarm or other alert mechanism.The NC20M00273KBA is an extremely versatile and reliable temperature sensor, and is suitable for a wide range of temperature sensing and monitoring applications. It is also relatively easy to use, making it a popular choice for electronic designers and engineers looking for an accurate and cost-effective temperature sensor.
