NTC thermistors, also known as negative temperature coefficient thermistors, are temperature-sensitive resistors with negative temperature coefficients. NTC thermistors are widely used in temperature measurements.

The ABNTC-0402-472J-3950F-T is a type of NTC thermistor. Such thermistors are commonly used in temperature measuring applications, such as home appliances, medical equipment, and automotive electronics. This thermistor has a resistance of 3950 ohms at 25°C, which is commonly used for temperature measurement in the 10 to 60°C range.

The working principle underlying NTC thermistors is based on the temperature-dependent electrical resistance of the positive temperature coefficient (PTC) material. The resistance of PTC materials increases with temperature. Conversely, NTC materials exhibit decreased resistance with increasing temperature. NTC thermistors are commonly constructed from sintered mixtures of metal oxides, and their resistance value and temperature-dependent characteristics are determined by the composition of these mixtures.

When an NTC thermistor is placed in an electrical circuit, current will flow through the thermistor and a voltage drop will occur across its terminals. The voltage drop will increase as the temperature of the thermistor rises. This property of the thermistor can then be used to measure the ambient temperature. In the ABNTC-0402-472J-3950F-T, the voltage drop across its terminals is approximately 11.7mV/°C at 25°C.

In addition to temperature measurement, NTC thermistors can be used in other applications. For example, they can be used as current-limiting devices in circuits, and can be used to protect sensitive electronics from overload. NTC thermistors can also be used to detect the temperature of motors or other equipment, providing an indication of motor overload or other safety concerns. In some cases, they may even be used to measure changes in relative humidity, by using them as humidity transducers.

In short, the ABNTC-0402-472J-3950F-T is a type of NTC thermistor used in temperature measurement applications. The thermistor works by changing its resistance depending on the ambient temperature, allowing for precise temperature measurement. The thermistor can also be used in other applications, such as current limiting, motor overload detection, and humidity transduction.
