NTC thermistors are a special type of temperature sensors that typically change their resistance value in response to changes in the temperature around them. The B57164K0221J052 NTC thermistor is one such device, typically used in automotive, industrial, and consumer applications. This article will explain the application field and working principle of B57164K0221J052.

Application Field

The B57164K0221J052 is a NTC thermistor that is designed for use in automotive, industrial, and consumer applications such as temperature sensing, liquid level detection, motor protection, and motor control. It is designed for operation over a wide temperature range and has excellent temperature stability over its operating temperature range. It is also well suited for applications which require high accuracy and reliability.

For automotive applications, B57164K0221J052 is typically used in the engine control unit (ECU) and anti-lock braking system (ABS). It is used to detect the temperature within the engine and ABS system and shut down the system in case of overheating. This helps to prevent overheating and other problems caused by excessive temperatures.

For industrial applications, B57164K0221J052 can be used in temperature control applications such as controllers and regulators. It is also used in motor protection applications such as surge protection and overcurrent protection.

In consumer applications, B57164K0221J052 is used in ovens, stoves, refrigerators, and washing machines. In these appliances, the thermistor senses the temperatures within them and ensures that the appliance does not overheat.

Working Principle

NTC thermistors are temperature-sensitive resistance elements which exhibit a change in electrical resistance when exposed to a change in temperature. The B57164K0221J052 is a type of NTC thermistor which exhibits a negative resistance coefficient (a decrease in resistance with an increase in temperature) on heating.

The resistance of a B57164K0221J052 thermistor is given by the following equation: R=Ae^-B/T , where A and B are the parameters of the thermistor, T is the temperature, and R is the resistance. As the temperature of the thermistor increases, the resistance decreases.

When the B57164K0221J052 is used in a circuit, it is typically connected in series. This allows current to flow through the thermistor and its resistance changes in response to temperature changes. The change in resistance is picked up by the circuit and is used to measure the temperature of the thermistor.

Conclusion

The B57164K0221J052 is a NTC thermistor designed for use in automotive, industrial, and consumer applications. It exhibits a negative temperature coefficient (NTC) and its resistance decreases with an increase in temperature. The resistance of the thermistor can be measured using a circuit and can be used to detect temperature changes in the application.
