Introduction

This article will introduce a type of inductor,PL8181NL, from the category of Fixed Inductors. Firstly, this paper will introduce the working principle of PL8181NL. Secondly, the application fields will be discussed. At last, this paper will give a brief conclution.

Working Principle

PL8181NL is a type of fixed inductor, which used for electronics usually. This kind of inductor is a mixture of the shape of the core and wire, and each element of the mixture will contribute a lot to this device. The strongest component of these components is the soft magnetic material core, which will reduce the resistance and allow the current to pass, reduce cofreqency loss and improve the anti-interference ability.

In the stator and rotating parts of the electromagnetic field, the stator is usually composed of iron, air gap, ferrum slurry elements. The rotor is wound with wires. When the current passes through the output winding, the magnetic field is generated, and then the electromagnetic induction is used to interfere with the rotating part, so that it can be used as power machine.

In addition, the method of permanent magnetization of the core can increase the reverse bias current of the diode. This means that the core with permanent magnetization needs no current to obtain the static magnetic field, which further reduce the power consumption and extend the power supply life.

Applications Field

The application field of PL8181NL can be divided into two categories: industrial and domestic applications. Industrial applications such as: UPS, solar and wind power generation systems, inverters, frequencies converters, high-power rectifiers, DC to DC converters, motors and generators control, photovoltaic inverters, welding machines, motor speed and frequency control, electric drive systems, electronic relays etc.

In home appliances, PL8181NL wide applied in TV sets, amplifiers, DVD, air conditioning, electric applicance, power source equipments, computer, modem, set-top-box and other products.

Conclusion

PL8181NL is a type of fixed inductor from the category of fixed inductors. This kind of inductor could reduce the resistance and allow the current to pass, reduce cofreqency loss and improve the anti-interference ability. The application fields of PL8181NL are mainly in industrial and domestic appliances.
