A temperature sensor is an electrical device that is used to measure temperature changes and thermal expansion in a system. There are a variety of temperature sensors, each of which has advantages and limitations depending upon the applications and environments. The most popular temperature sensing devices are thermocouples, resistance temperature detectors (RTDs), thermistors, infrared (IR) thermometers, and pyrometers. In this article, we will be discussing the application field and working principle of B59548A0135A020, which is a PTC thermistor.

A PTC thermistor is a type of temperature-sensitive device made from a semiconductor material. It has a positive temperature coefficient, meaning it increases resistance as temperature increases. This type of thermistor is used in applications where high accuracy and fast response time are important. It is also used in applications that require temperature compensation. The B59548A0135A020 is a surface-mountable NTC thermistor which consists of two lead-free terminals.

The application field of the B59548A0135A020 PTC thermistor includes AC controllers, electronic thermostats, contactors, relays, and other temperature-sensing equipment. It is used in these applications as an over-temperature safety device for controlling current or protecting circuits. Additionally, PTC thermistors are used as a temperature-dependent resistor to measure temperature in circuit boards. It is also used to detect temperature changes in various types of heaters, refrigeration systems, and other home appliances like microwaves and electric ovens.

The working principle of the B59548A0135A020 PTC thermistor is based on the behavior of semiconductor minute particles in outer space when the temperature changes. These particles are subjected to thermal expansion and contraction as the temperature rises and falls. This process is used to regulate the current flow and determine the amount of resistance. As temperature rises, the particles become more conductive, reducing the resistivity and allowing higher current flow. Conversely, as the temperature drops, the particles become less conductive, increasing the resistivity and reducing the current flow.

The B59548A0135A020 PTC thermistor is a temperature sensing device which has high accuracy and fast response time. It is ideal for applications that need to measure a wide range of temperatures. It is also used for temperature compensation and in AC controllers, electronic thermostats, contactors, and relays. The working principle of the PTC thermistor is based on the behavior of semiconductor minute particles in outer space when the temperature changes. This information should help you to better understand the application field and working principle of the B59548A0135A020 PTC thermistor temperature sensor.
