Fixed inductors are electronic components used to store energy by converting electrical energy into magnetic energy. They play an important role in the design of electronic circuits. One of the most commonly used fixed inductors is the PL8708. This inductor is designed for high current applications and is suitable for a wide range of applications.

The PL8708 is a multi-layer high power inductor, with a rated current range of 2.2 A to 10 A. Its inductance values range from 220 nH to 2.2 mH, and it has a low level DCR of 0.117 mΩ. The inductor is packaged in a SMT type, which makes it easier to be mounted on small PCBs. The high temperature grade of the PL8708 also allows it to operate at higher temperatures, up to 125°C.

The PL8708 can be used for a variety of applications. It is suitable for high power circuits, such as LED lighting and automotive electronics. It is also widely used in switching power supplies, DC/DC converters, and audio amplifier circuits. In addition, the PL8708 can be used as a choke inductor in RFID circuits.

The working principle of the PL8708 is based on the electromagnetic induction. When a conductor passes through a magnetic field, an electromotive force is induced in the conductor, which generates an electrical current. The current in the conductor increases as the magnetic flux, or the number of magnetic lines, increases. In the case of PL8708, the magnetic flux is generated by the core of the inductor, and the current is induced by the conductor wound around the core. By controlling the current, the inductance of the PL8708 can be adjusted.

The main advantages of using the PL8708 are its high current capacity, high inductance values, and low DCR. As mentioned earlier, the rated current range of the PL8708 is 2.2 A to 10 A, which makes it suitable for higher power circuits. The low DCR ensures that the magnetic flux generated is sufficient to induce the current in the conductor. The inductance values range from 220 nH to 2.2 mH, making it suitable for a wide range of applications.

In conclusion, the PL8708 is an ideal choice for high power applications due to its high current capacity, high inductance values, and low DCR. It is suitable for various applications, such as LED lighting, automotive electronics, switching power supplies, DC/DC converters, audio amplifier circuits, and RFID circuits. The working principle of the PL8708 is based on electromagnetic induction, and it can be used to adjust the inductance values of the inductor.
