PTC thermistors, also known as positive temperature coefficient thermistors, are increasingly being used to measure temperature in environments prone to problems associated with traditional thermometers such as thermocouples and resistive temperature detectors (RTDs). PTC thermistors, which measure temperature using the electrical properties of their ceramic material, offer an efficient design solution to many temperature-sensing applications.

The most common type of PTC thermistor is the B59885C0120A051, generally referred to as the B59885. This device is specifically designed for use in a wide variety of temperature sensing applications, including industrial, automotive, medical, and consumer products.

The B59885 is a glass-encapsulated, bead-shaped thermistor made of a specialized ceramics material. Its shape makes it ideal for use in many applications where there is limited space such as in automotive and consumer electronics. Its size also makes it suitable for use in handheld devices. In addition, the device is highly reliable due to its stability even in harsh industrial dynamics such as high vibration and high temperature.

The B59885 has a ceramic sensitization temperature of +10° C and a thermal sensitivity of about 0.2° C/W. It is particularly well-suited for high temperature applications, as it can reliably measure temperatures up to +250° C. In these applications, it offers a linear, reliable, and repeatable response to temperature changes and is often used as the main temperature sensor in industrial applications.

The working principle of the B59885 is based on the change in electrical resistance when the temperature changes. When the temperature increases, the resistance of the ceramic material increases, and when temperature decreases, the resistance decreases. By measuring the resistance with an electrical circuit, it is possible to accurately measure the temperature of the environment. The device has a high response time compared to traditional thermocouples and other temperature sensors, allowing it to capture rapid temperature changes.

The B59885C0120A051 PTC thermistor has a wide range of applications in various industries due to its reliable performance and small size. It is often used in automotive and industrial applications for temperature control and management, including in engine control systems and fuel pumps. It is also used in medical applications for patient body temperature monitoring and in consumer electronics to manage temperatures in television sets, laptops, and mobile phones.

In summary, the B59885C0120A051 PTC thermistor is a reliable and versatile temperature sensor that is well-suited for use in a variety of applications. Its ability to accurately measure temperatures up to +250° C along with its small size makes it a popular choice for industrial, automotive, medical, and consumer applications.
