Temperature sensors are vital components of electronic devices, providing important data that allows system stability and efficiency. NTC (Negative Temperature Coefficient) thermistors are a type of thermistor which, as their name implies, have a resistance that decreases as temperature increases. Among the various temperature sensors available today, NTC thermistors are the most widely used, and can be found in virtually every sector of modern industry, from consumer electronics to industrial and automotive applications. The PR302J2 is an NTC temperature sensor designed to deliver accurate, reliable readings.

The PR302J2 is a reliable thermistor with high accuracy and stability over a wide range of temperatures. The sensor has a wide temperature range from -40°C to +120°C, making it suitable for both low-temperature cooling and high-temperature heating applications. It has excellent resistance stability to temperature changes, with a low coefficient of about 0.5%/°C. The accuracy of the PR302J2 is also exceptional, with typical deviation from its temperature-resistance curve of ±0.2% over the entire -40°C to +120°C range.

One of the most common applications for the PR302J2 is as an automotive air temperature sensor. This type of sensor is used to measure the temperature within the engine’s intake air system, providing data necessary for the engine control unit to maintain optimal engine performance. The PR302J2 proves to be an excellent choice for this application because of its high accuracy and stability over a wide temperature range. This sensor is also highly resistant to environmental contaminants such as dust and other particles, which is important in a harsh automotive environment.

The working principle of an NTC thermistor is based on the principle of resistive temperature measurement. In an NTC thermistor, the resistance decreases as the temperature increases, forming a negative temperature coefficient. The PR302J2 utilizes this principle to deliver accurate, reliable temperature measurements. The working principle is quite simple: the thermistor is connected in series with a fixed resistor, and a voltage is applied across these two components. As the temperature of the thermistor increases, its resistance decreases, changing the overall resistance of the circuit. This change in resistance can then be used to determine the temperature.

The PR302J2 is a reliable NTC thermistor which is widely used in modern industrial and automotive applications. With its wide temperature range and high accuracy and stability, the PR302J2 is an ideal sensor for a wide range of applications. Its working principle is based on the principle of resistive temperature measurement, enabling it to accurately measure temperature changes. With its excellent performance across a wide range of temperatures, the PR302J2 is an important component of modern electronic devices.
