NTC Thermistors are temperature sensors that detect and respond to changes in temperature. They work by having a temperature-sensitive material (usually ceramics with metal contacts) that changes its resistance as the temperature rises or falls. This resistance change is converted into a voltage or current change that is measured and correlated to the temperature.

The PW222J2 is a NTC thermistor temperature sensor designed to measure and detect temperature changes over a wide range of temperatures (-40°C to 125°C). It operates based on the principle that the electrical resistance of a thermistor changes with temperature. The PW222J2 has a wide resistance range, making it suitable for various uses such as temperature control, temperature measurement, and thermal protection in many electrical and electronic devices.

The PW222J2 is a Negative Temperature Coefficient thermistor (NTC), meaning that its resistance decreases as the temperature rises. It operates with an excitation voltage of 5V and has a built-in current-limiting resistor that limits the maximum current to 5mA in order to prevent damage to the thermistor. The operating temperature range of the PW222J2 is -40°C to 125°C and it is able to measure temperatures with an accuracy of up to ±1°C. The size of the PW222J2 is 25.4mm x 4.8mm and it has a lead length of 120mm.

The PW222J2 has a very broad application field and can be used for various uses such as temperature control, temperature measurement, and thermal protection. It is commonly used in various consumer electronics, industrial, and automotive applications. In the automotive industry, PW222J2 thermistors are used in automotive electronic control systems to detect and monitor engine temperature. In consumer electronics, PW222J2 thermistors are used to control the amount of heat generated in order to prevent overheating and protect sensitive components. In the industrial sector, PW222J2 thermistors are used to detect temperature in a wide range of industrial applications, such as heating and cooling systems and industrial burners.

The working principle of the PW222J2 is based on the fact that its resistance decreases as the temperature rises. It utilizes an excitation voltage of 5V in order to measure the change in its resistance. The difference in resistance is then converted into a voltage or current change that is measured and correlated to the temperature reading. The measured temperature reading is then used to control various operations, such as the amount of heat generated, the speed of a fan, or the functioning of a cooling system.

In summary, the PW222J2 is a NTC thermistor temperature sensor designed to measure and detect temperature changes over a wide range of temperatures (-40°C to 125°C). It has a wide application field and is commonly used in various consumer electronics, industrial, and automotive applications. The working principle of the PW222J2 is based on the fact that its resistance decreases as the temperature rises. It utilizes an excitation voltage of 5V in order to measure the change in its resistance, which is then converted into a voltage or current change that is measured and correlated to the temperature reading.
