Temperature Sensors - NTC Thermistors, also known as negative temperature coefficient thermistors, are electronic components that are used to measure temperature. The B57869S0302F140 is one such thermistor, and its application field and working principle can best be outlined in the following sections.

Applications

The B57869S0302F140 is a specially-designed NTC thermistor, which is targeted for use as a temperature sensing component in various electronic systems and devices. This thermistor is popular for use in computers and TVs, as it is designed to monitor the temperature of components within the system. It is also used in medical devices, temperature controllers, and various other electronic devices. The B57869S0302F140 is a particularly useful component because it is designed to have a small physical size, which makes it ideal for use in small spaces, such as inside electronic components. In addition, this thermistor is designed with a resistance-to-temperature relationship which is stable over time, and so it can be used with confidence even in long-term applications.

Working Principle

The working principle of the B57869S0302F140 is fairly straightforward. The thermistor is essentially a circuit component with a built-in resistor. As the temperature changes, the resistance of the thermistor changes as well. This is due to the fact that the material from which the thermistor is made is sensitive to temperature. For example, a thermistor may have a resistance of 100 ohms at 25° Celsius. As the temperature increases, the resistance of the thermistor will increase as well. The resistance change is usually linear, meaning that the resistance will increase at a consistent rate with increasing temperature. This allows the thermistor to be used as a temperature sensor, as the resistance can be used to indicate the temperature.

Conclusion

The B57869S0302F140 is a widely-used NTC thermistor, which is especially popular for its tiny physical size and its stable resistance-to-temperature relationship. It is designed for use as a temperature sensing component in various types of electronic devices and systems, and its working principle can best be summarized by understanding its linear resistance-to-temperature relationship.
