Working Principle

The B57621C222J62 thermistor works under the principle that the resistance of a semiconductor decreases with temperature. It is a semiconductor that maintains its resistance even at very high temperatures. As the temperature rises, its resistance decreases, and as the temperature falls, its resistance increases. This change in resistance is predictable and reliable, making it reliable and ideal for temperature sensing and controlling.

The thermistor is a two-terminal device that operates on the principle of temperature-dependent conduction. The thermistor is constructed of a semiconductor material such as doped silicon or germanium and an external lead wire. When this thermistor is exposed to changes in temperature, it produces a change in its electrical resistance that is proportional to the temperature change.

The B57621C222J62 is designed in such a way that its resistance decreases with increasing temperature, so it can be used in applications where the temperature needs to be monitored and controlled. The thermistor can be used in both analog and digital circuits to measure temperature and provide feedback for temperature regulation.

In conclusion, the B57621C222J62 thermistor is a type of NTC thermistor suitable for a wide temperature range, from -50°C to +150°C. It is commonly used in a variety of temperature sensing and control applications, such as temperature control for HVAC systems, power supplies, electronic circuit boards, and motor control circuits. It works on the principle of temperature-dependent conduction, with its resistance decreasing with increasing temperature.
