Temperature Sensors - NTC Thermistors

A temperature sensor consisting of a Negative Temperature Coefficient (NTC) thermistor is used to measure temperature in many fields. It is an electrical device whose resistance changes proportional to the temperarure to which it is exposed. NTC thermistors are typically made of a semiconductor material such as siclicon or ceramic, featuring a fairly low resistance at room temperature. As the temperature of the thermistor increases, the resistance decreases and vice versa; at certain temperatures the NTC thermistors reach a point of zero resistance.

B57621C474J62 Application Field and Working Principle

The B57621C474J62 thermistor is a commonly used negative temperature coefficient (NTC) thermistor. It is specifically designed for precise and accurate temperature measurements, with a high precision of 0.3 degrees Celsius. This particular thermistor is commonly used in various applications such as industrial temperature controlling, temperature detecting in automobiles, temperature measuring in home and building applications, and so on.

In terms of working principle, the B57621C474J62 thermistor uses the change in electrical resistance to measure temperature changes. It works by converting a temperature change to generate a voltage. The voltage generated can be used to indicate the temperature change in an circuit. As the temperature of the thermistor increases, the resistance decreases. The negative temperature coefficient (NTC) indicates that as the temperature rises, the resistance decreases so that a greater amount of electrons flow through and produce a greater current output in an circuit. The NTC thermistors have a high resistance at low temperatures, allowing for very accurate measurements in a wide range of temperatures.

Overall, the B57621C474J62 thermistor is able to offer a precise and accurate readings of temperature in many applications, such as temperature controlling, detecting in automobiles, and measuring in home and building applications. This particular thermistor features a high precision of 0.3 degrees Celsius, making it an excellent choice for sensitive temperature measurements.
