Temperature sensing has become an integral part of everyday life, whether at home, work, or while commuting. NTC thermistors are one type of temperature sensor that is widely used in temperature sensing applications. One such thermistor is the NB20N00823KBA, which is designed to measure temperature in the range of -50 to 100 °C. This article will focus on the application field and working principle of the NB20N00823KBA.

The NB20N00823KBA is particularly suited for environments where accuracy, stability, and flexibility are of utmost importance. Its range of -50 to 100 °C makes it ideal for temperature measurement in consumer electronics, HVAC/R systems, industrial automation, medical equipment, and aerospace. In addition, its small size (19.05 x 9.52 x 6.35 mm) and low weight (14.5g) make it suitable for applications where space and weight are at a premium.

The NB20N00823KBA utilizes a Negative Temperature Coefficient (NTC) thermistor to detect temperature changes. A thermistor is a semiconductor device whose resistance changes in response to temperature variations. The NB20N00823KBA has an NTC thermistor with a nominal resistance of 10KΩ at 25°C, a B-value of 3950K, and a dissipation factor of 1mW/°C. This thermistor is molded into a stainless steel tube and is hermetically sealed to protect the thermistor from external elements.

The working principle of the NB20N00823KBA is based on the relationship between resistance and temperature. The NTC thermistor within the device has a negative temperature coefficient, meaning that its resistance decreases as temperature increases. As the temperature of the surrounding environment changes, the thermistor’s resistance changes accordingly. This change in resistance is detected by an internal circuit, which converts it to an equivalent temperature value and sends it to the output.

To summarize, the NB20N00823KBA is a temperature sensor based on an NTC thermistor that is ideally suited for environments where accuracy, stability, and flexibility are paramount. Its range of -50 to 100°C makes it suitable for a variety of temperature sensing applications, and its small size and low weight allow for installation in limited spaces. Its working principle is based on the relationship between resistance and temperature, such that the thermistor’s resistance decreases as temperature increases.
