Temperature Sensors – NTC Thermistors

Thermistors are sensors used to measure temperature ranges between -200 and +1300 degrees Celsius, and often used in temperature control circuits. Among the different type of thermistors one of the most popular is the Negatively Temperature Coefficient (NTC) thermistor. An NTC thermistor is a thermally sensitive resistor with a negative temperature coefficient of electrical resistance which relies on their ability to change their resistance depending on their body temperature. The higher the temperature, the lower their resistance due to their negative temperature coefficient. The CWF4B272F3100 is an NTC thermistor, optimized for special temperature ranges, and typically used in applications where an accurate reading is desired. This thermistor is made out of ceramic and includes two metal contacts. This type of thermistor has a higher perception of temperature than 3-terminal thermistors due to its low series resistance, making it an ideal choice for applications where accuracy of temperature measurement is important. The CWF4B272F3100 is mainly used in applications where accurate temperature readings are needed in a wide variety of products like cars, air conditioners, dishwashers, etc. It is suitable for temperature ranges between -20 and +130 degrees Celsius, with a wide temperature sensing range and a very high degree of accuracy and repeatability. It is also suitable for high-temperature and low-temperature applications, where low traffic is needed and good accuracy is required. The working principle of the CWF4B272F3100 thermistor is based on the principle of temperature coefficient, which means that the resistance of the thermistor changes in response to a change in temperature. This thermistor has a negative temperature coefficient, which means its resistance decreases when the temperature increases. In addition, the CWF4B272F3100 thermistor also has a high accuracy and repeatability, meaning that it will consistently give an accurate temperature reading even in various environmental conditions. This thermistor also has a low series resistance which helps ensure an accurate temperature reading despite any current leakage. Overall, the CWF4B272F3100 thermistor can be used in a wide range of temperature sensing applications due to its temperature coefficient and its high accuracy and repeatability. Therefore it is a popular choice for temperature sensing applications that require higher accuracy and repeatability than 3-terminal thermistors.
