N8229WN

The N8229WN is a type of PTC thermistor that is used for over-current and over-temperature protection, and is typically produced and used for commercial and industrial applications. It has a wide operating temperature range from -25℃ to 80℃, and is capable of operating with both AC and DC situations. The N8229WN is characterized by its low cost and reliability, and is very popular in use in production.

This PTC thermistor functions by switching to its high-impedance state when a current higher than the rated value is detected, creating a protection circuit to simultaneously cut off the power source and protect the electrical circuit. Its ability to reset itself to its low-impedance off state when the temperature drops indicates its resilience and suitability for commercial and industrial usage.

The N8229WN PTC thermistor offers a wide range of primary functions and can serve a number of different applications. In the fields of Avionics, Telecoms, Robotics, Power Supplies,Uninterruptible Power Supplies (UPS) and Motor Control, a N8229WN can be used as a safety switch, disconnecting the power source as soon as the rated current is exceeded. In addition, it is often used as a tempestor in batteries and game console cooling systems, as well as in automotive applications such as electric fuel pumps and fuel injection systems.

The working principle behind the N8229WN is fairly simple and easy to understand. When the temperature increases, the positive temperature coefficient (PTC) increases, the impedance decreases, and the current increases, making it easier for a greater current to flow to the PTC thermistor. This causes the PTC to heat up, and the impedance to rise again, limiting the current flow. The result is a thermal protection circuit that can safely handle high loads and prevent circuit damage.

In conclusion, the N8229WN is a type of PTC thermistor specifically designed for over-current and over-temperature protection, and exhibits excellent performance at a low cost. With a wide range of applications, the N8229WN is a great choice for commercial and industrial usage. Its simple working principle and easy to use capabilities make it an ideal choice for those looking to implement a cost-effective but reliable circuit protection solution.
