NB20J00472KBA

Temperature Sensors - NTC Thermistors

The NB20J00472KBA is an NTC thermistor, which is a type of temperature sensor. Thermistors are very accurate and reliable temperature sensors that respond quickly to temperature changes, making them ideal for a variety of applications. One of the applications that they are used in is temperature measurement and controlling systems. In this application, the thermistor operates as a negative temperature coefficient (NTC) resistor with a predictable electrical resistance change due to temperature changes. NTC thermistors are capable of accurately measuring temperatures in the range of -55°C to +125°C.

Thermistors are made up of specially formulated ceramics that exhibit a high temperature coefficient of electrical resistance as temperature increases or decreases. The NB20J00472KBA is an NTC thermistor with a nominal resistance of 4.7k ohms at 25°C and a negative temperature coefficient of -3.9% per °C. This means that the resistance will decrease as the temperature increases, and vice versa. The response of thermistors can be tuned to specific application requirements by selecting the appropriate material and size.

The NB20J00472KBA is a small NTC thermistor that is designed for low-power applications. It is characterized by its ability to provide accurate and reliable temperature measurements over a wide temperature range. Its small size and low power consumption make it an ideal choice for applications where space and power are limited. It is also suitable for use in applications in which temperature changes need to be accurately measured and controlled.

The working principle of NB20J00472KBA is quite simple. When a voltage is applied across the two terminals of the thermistor, a current flows in proportion to the resistance of the thermistor. As the temperature changes, the resistance of the thermistor changes, and the corresponding current also changes. This change in current can then be measured by an external device, such as an amplifier, to determine the temperature.

In conclusion, the NB20J00472KBA is an NTC thermistor that is designed for use in temperature measurement and controlling systems. It is characterized by its small size, low power consumption and accurate temperature measurement capabilities over a wide temperature range. Its simple working principle enables it to be easily integrated into a variety of temperature measurement and controlling applications.
