NTC thermistors are devices which measure temperature through its resistance change in accordance to the temperature. They exhibit a negative temperature coefficient of resistance (NTC for short), as the temperature increases the resistance decreases. The B57621C224K62 is a particularly popular NTC thermistor which is widely used in a range of industrial and commercial heating and cooling applications as well as automotive system regulation.

The B57621C224K62 is an encapsulated, axial leaded, glass-bodied NTC thermistor. It has a resistance of 22.4K at 25°C and can work up to a maximum of 220°C making it ideal for a range of applications involving high temperature temperature sensing. The device is known for its excellent cycling characteristics and stability over a wide temperature range and is rated for class B thermistor accuracy of 1% and a power dissipation of 0.6W.

The B57621C224K62 can be used to regulate the flow of coolant in automotive engines, as well as providing accurate temperature resolution in consumer appliances such as washing machines and fridges, regulating fluid flow in cooling systems and monitoring performance in electronic equipment and medical systems.

The working principle of the B57621C224K62 is fairly simple. This device is composed of a metal oxide bead, which can be either a lead or a tin oxide, and a ceramic core. The core and bead are connected by two long wires and the beads are positioned close so that the resistance between them will change when the temperature changes.

The thermistor works by changing its resistance in accordance with its temperature. As the temperature increases, so does the electron mobility of the oxide, this is then followed by a decrease in the resistance of the thermistor. When the temperature decreases, the oxygen molecules slow, resulting in an increase in resistance. This change then allows the device to sense different temperatures and convert them into electrical signals.

The B57621C224K62 is an extremely durable and reliable temperature sensing device which is suitable for a variety of different applications with its excellent cycling characteristics and high temperature range. It is particularly ideal for automotive engines and consumer appliances due to its accurate temperature resolution and excellent cycling characteristics. This device is also popular among medical professionals, as it is able to provide accurate temperature readings in both medical tests and surgeries.
