NTC thermistors are one of the most commonly used temperature sensors, and the B57861S0103H040 is a typical NTC thermistor. This thermistor is a negative temperature coefficient thermistor, meaning that when the ambient temperature increases, the resistance decreases. The B57861S0103H040 thermistor is widely used in many applications, such as temperature measurement and temperature control.

Application field

The B57861S0103H040 thermistor can be used in a variety of applications, from automotive, industrial, and consumer industries. In automotive applications, the thermistor can be used to detect and control the temperature of car engines, providing protection against overheating. In industrial applications, the thermistor can be used to control the temperature in industrial equipment and machinery, to maintain optimal working conditions. In consumer electronics, the thermistor is used in various devices such as refrigerators, washing machines, ovens, and air conditioners, to detect the ambient temperature and adjust settings accordingly.

Working principle

The B57861S0103H040 thermistor works by changes in resistance when the ambient temperature changes. The thermistor is a semiconductor, whose resistance to the flow of electricity changes when the temperature changes. As the temperature increases, the resistance of the thermistor decreases. This change is caused by the movement of electrons within the semiconductor, which move faster with increased temperature, resulting in an increased flow of electricity, and therefore, a decrease in resistance. This change in resistance can be measured and used to determine the ambient temperature.

The B57861S0103H040 thermistor is suitable for use in applications where a reliable temperature sensor is essential, such as automotive, industrial, and consumer electronics. The thermistor’s working principle is simple but effective, and can be used to accurately measure and control the temperature in a variety of applications.
