PTC (positive temperature coefficient) thermistors are temperature-sensitive semiconductor components that are widely used in many different applications due to their low cost, high accuracy, and fast response time. The B59421A0085A062 is a PTC thermistor manufactured by PerkinElmer and is commonly used in temperature sensing and control applications. This thermistor has a resistance-temperature coefficient of 0.85 ohms per degree Celsius and is a low-resistance device for measuring temperatures from -40 to 125° C.

The working principle of a PTC thermistor is based on the fact that its resistance increases with increasing temperature. This increase in resistance occurs as a result of the electrons inside the thermistor being excited by heat energy and moving from bound states to free states. When the number of free electrons increases, the resistance of the device increases as well. The resistivity of the thermistor is determined mainly by its temperature coefficient, which is the amount of change in resistance per degree Celsius. The B59421A0085A062 has a resistance-temperature coefficient of 0.85 ohms per degree Celsius.

The B59421A0085A062 is often used in automotive, electronic, and medical applications where temperature sensing and control are important. In automotive, this thermistor can be used to monitor and regulate the heat generated by the engine, helping to ensure optimal performance. Likewise, it can be used to measure the temperature of electronic devices, such as computers and televisions, to ensure that they are running efficiently and safely. In the medical industry, this thermistor can be used to measure the temperature of body parts, such as fingers and toes, to detect potential health problems and aid in the diagnosis of certain conditions.

In addition to automotive, electronic, and medical applications, the B59421A0085A062 PTC thermistor can also be used in many other industries. For example, it can be used to monitor and regulate the temperature in industrial processes, such as soldering and welding, or for outdoor temperature sensing applications like weather stations. This thermistor is also used in some consumer products, like space heaters and refrigerators, to measure the temperature of their internal components.

Overall, the B59421A0085A062 PTC thermistor is a reliable and accurate temperature sensing device that can be used in a variety of applications. It has a low resistance-temperature coefficient of 0.85 ohms per degree Celsius, which allows it to accurately measure temperatures ranging from -40 to 125° C. It is also easy to install and use, making it a popular choice for automotive, electronic, medical, industrial, and consumer applications. As such, this thermistor is well-suited for many temperature sensing and control applications.
