PTC thermistors, short for Positive Temperature Coefficient Thermistor, are temperature sensors that come in different models and configurations. They are commonly used in temperature control applications such as household appliances, car components, and computer peripherals. Among the different PTC thermistors, TFPT0805L1801FV thermistors are some of the most popular. In this article, we will discuss the application fields and the working principle of a TFPT0805L1801FV thermistor.

A TFPT0805L1801FV thermistor is a type of PTC thermistor with a flat disk shape. It has an operating temperature range of -40 to +125 degrees celsius, with a tolerance of +/-1.5K. Its resistance at 25 degrees celsius is 1.8 Ohms, it has a power dissipation of 0.25 W, and a max temperature of 130 degrees celsius. It comes in a TO-263 package which has a lead spacing of 2.67mm and a body length of 5.3mm.

TFPT0805L1801FV thermistors are widely used in temperature control applications. For example, they can be used in industrial machinery, such as over-temperature protection, or to detect malfunctions in machines. They are also used in consumer products, such as food preparation and preservation, to detect incorrect temperature settings. In automotive applications, they are used to monitor the temperature of car components, such as the engine coolant and the oil filter. Additionally, they are used in computer peripherals, such as keyboards and monitors, to prevent overheating.

The working principle of a TFPT0805L1801FV thermistor is based on the fact that its resistance changes with temperature. It is made of a semiconductor material, such as ceramic or silicon, that has a positive temperature coefficient. This means that when the temperature increases, the resistance of the thermistor increases as well. When the temperature changes, the thermistor’s resistance changes accordingly, and this change in resistance can be used to measure the temperature.

In conclusion, TFPT0805L1801FV thermistors are widely used in temperature control applications. They have a flat disk shape, an operating temperature range of -40 to +125 degrees celsius, a resistance of 1.8 Ohms at 25 degrees celsius, and come in a TO-263 package. The working principle of a TFPT0805L1801FV thermistor is based on the fact that it is made of a semiconductor material with a positive temperature coefficient. As the temperature increases, the resistance of the thermistor increases, which can be used to measure the temperature.
