Working Principle of B57869S0302G140

The B57869S0302G140 thermistor uses the principle of negative temperature coefficient (NTC). When the temperature of the surrounding environment changes, the resistance of the thermistor varies inversely with the temperature. The thermistor is made of a sintered mix of metal oxide and other materials, which has a non-linear resistance-temperature relationship. When the temperature of the environment changes, the resistance of the thermistor changes according to a known mathematical equation. This equation is known as the Steinhart-Hart equation. The equation is used to quantify the resistance-temperature relationship of the thermistor and is used in many temperature sensing and measurement applications.

Conclusion

B57869S0302G140 thermistors are negative temperature coefficient (NTC) sensors which are used in many temperature sensing and measurement applications. They are suitable for precision temperature measurement and control, temperature measurement in automotive applications, and temperature control in consumer electronics, communications equipment, industrial equipment, medical equipment, and home appliances. The thermistor uses the Steinhart-Hart equation to calculate the resistance-temperature relationship of the thermistor.
