Temperature Sensors - PTC Thermistors has become a widely used and reliable technology in many applications, and TFPT1206L4700JV is one of the PTC thermistors. It is mainly used in power electronics protection, with a limit of 12A and a junction temperature of 150 °C. PTC thermistors can regulate the temperature from the higher range to the lower range and the resistance is increased when the temperature goes up. Therefore, they can act as a protection device to limit the temperature rise of the electronic component. In addition to power electronics, TFPT1206L4700JV can also be used in the automotive industry, industrial applications, and domestic appliances.

The structure of the TFPT1206L4700JV is composed of a semiconductor with a PTC resistor element surrounded by an insulating sleeve. The main working principle is that the resistance increases with temperature. When the temperature exceeds a certain level, the thermistor changes from low resistance state to high resistance state, thus limiting the current flow and inhibiting the temperature rise. For the TFPT1206L4700JV, if the current exceeds the rated value, the temperature will increase rapidly and the resistance value will also increase rapidly. Therefore, the power electronics protection device with this thermistor can effectively limit the current and protect the electronic component.

Another important application field of TFPT1206L4700JV is AC/DC power conversion and energy conversion. This thermistor is used in the AC/DC power converter to control the current rate and limit the power current. When the current is higher than the rated value, the thermistor can limit its passing current to the rated value, thus achieving efficient power conversion.

In summary, the TFPT1206L4700JV has a wide range of applications in different fields. Its main working principle is to regulate the temperature. When the current exceeds a certain limit, the resistance will increase quickly. This thermistor is suitable for power electronics protection and AC/DC power conversion. The main advantages of this thermistor are its high temperature stability, excellent temperature coefficient, and long-term reliability.
