Temperature Sensors - PTC Thermistors
PTC thermistors are temperature sensors that use positive temperature coefficient (PTC) materials for measuring temperature. A PTC thermistor is made from semiconductors whose resistance increases as temperature increases. They are typically used in applications such as temperature switch, temperature regulation, over-temperature protection, and current overheat protection.
The PRF18BB471QB5RB is a high-precision, NTC thermistor, which is a thermistor with a negative temperature coefficient. It has a resistance value of 4.7kΩ at 25℃, and a B value of 3380K. It is capable of accurately measuring temperature changes within a wide temperature range, ranging from -40℃ to 85℃. It has a very low temperature coefficient of resistance (TCR) of less than 100ppm/℃, providing very stable, accurate, and reliable temperature measurements. The PRF18BB471QB5RB is also available in various packaging options, including a very small SOT-23 package.
The PRF18BB471QB5RB thermistor can be used in a variety of applications, such as temperature switch, temperature regulation, over-temperature protection, and also current overheat protection.
The main advantage of the PRF18BB471QB5RB is its quick response time. It has a very fast response time of typically less than 1 second. It can also be operated in high temperature environments up to 85℃ without any major performance degradation. It also has a very high accuracy of ±1℃.
The working principle of the PRF18BB471QB5RB thermistor is based on the PTC characteristics of the semiconductor materials. As the temperature increases, the resistance of the thermistor increases. This increase in resistance creates a voltage drop across the thermistor which can be detected and measured by appropriately connected electronics.
The PRF18BB471QB5RB thermistor is one of the most accurate and reliable temperature sensors on the market. It has a fast response time and a wide temperature range, making it an ideal choice for various applications such as temperature switch, temperature regulator, and over-temperature protection. Additionally, its major advantages include high accuracy, quick response time, and long working life.
