Temperature Sensors - PTC Thermistors

PTC thermistors are one of the most popular types of temperature sensors used in industrial applications. They are widely used in appliances, electronics and automotive applications. PTC thermistors have a Positive Temperature Coefficient (PTC) which means that when the temperature of the device is increasing, its resistance increases too.The PTC thermistor of choice for many applications is the TFPT1206L1200FV. This particular PTC thermistor is the smallest in its class, making it especially useful in space-restricted applications. It is also designed to work within a wide temperature range, from -40°C to 85°C.The TFPT1206L1200FV has several typical applications. These include use as a temperature sensing switch for detecting temperatures in various appliances and electronic devices. It is also used in motor temperature protection applications, where it is relied upon to accurately detect and protect motors in case of possible overheating. Another important application of the TFPT1206L1200FV is in thermostats, where it is used to detect temperatures and control the heating or cooling system of the house.The working principle of PTC thermistors is quite simple. They are made up of a semiconductor material that is sensitive to temperature. As the temperature increases, the resistance of the material also increases. This is because of the semiconductor material\'s Curie temperature, which is the temperature at which the semiconductor changes from insulator to conductor.When used in most applications, the TFPT1206L1200FV is designed to detect temperatures that are above the desired level. For example, in a motor temperature protection application, the thermistor is set to monitor for temperatures above a certain level. When the temperature is detected as being above this level, it will trigger the motor protection mechanism.In a thermostat application, the TFPT1206L1200FV will be used to detect if the temperature is too high or too low. When the temperature is detected as being too high or too low, it will trigger the thermostat to start heating or cooling the house.In conclusion, the TFPT1206L1200FV is a popular and versatile PTC thermistor used in many temperature-sensing applications. It is designed to detect and monitor temperatures in a wide range of industrial and consumer products. Its wide temperature range and small size make it useful in space-restricted applications. It is also reliable and easy to use in most applications.
