Introduction to Fixed Inductors

Inductors are basic electronic components used in various applications like audio signal processing including high and low pass filters, power supplies such as switching mode power supplies, and circuit protection. Fixed inductors are basic electronic components used in various applications like audio signal processing including high and low pass filters, power supplies such as switching mode power supplies, and circuit protection.The most common type of inductor is the fixed inductor. Fixed inductors consist of a coiled wire, often known as the winding, usually within a magnetic core made of ferromagnetic material and often contained in a sealed body. They are referred to as fixed because their inductance does not change with the application of an external voltage or a current of a certain frequency. For this reason, they are commonly used to maintain a constant impedance and current on a circuit.Among all kinds of inductors, PL8142NL is one of the most common ones, and has found numerous applications in audio systems. This article will discuss the application field of PL8142NL and its working principle in detail.

Application Field of PL8142NL

The PL8142NL fixed inductor has many applications in the audio system. It is primarily used as a power filter or power supply component, where its high inductance capability (up to 4.2mH) can help reduce the spikes and ringing on power supply. Additionally, it is suitable for most switching power applications such as portable power supply, AC/DC adopters & consumer electronics products.In audio systems, PL8142NL fixed inductors are also used to reduce EMI interference - low pass filters - from audio signals in both primary and secondary sides. It helps maintain a low parasitic capacitance, improving the frequency stability of circuits and reducing the inter-stage interference. Another application field of PL8142NL is the analog speaker box, which can greatly improve the stability and other properties of the speaker box, as it reduces the interference noise to a minimum level. It can also be used to extend the low-frequency range, and thus provide better sound quality.Finally, it can also be used in classic frequency filters and signal stabilization systems, especially in the voltage supply of a computer.

Working Principle of PL8142NL

The working principle of the PL8142NL fixed inductor is based on Faraday\'s law of induction. According to Faraday\'s law, when a conductor passes through a magnetic field, an electrical current is induced in the conductor due to the changing magnetic flux. When an electric current passes through a coil of wire, the resulting magnetic field creates a resistance to the flow of the current, referred to as inductive reactance. This resistance can be controlled by changing the number of turns of wire in the coil. The greater the number of turns, the greater the resistance to the flow of current. Thus, by increasing the number of turns, the inductance of the inductor can be increased.The PL8142NL fixed inductor has two sizes available. The larger size which is 10mm, provides the highest inductance value of up to 4.2mH. The smaller size which is 6mm, provide lower inductance value of up to 1.4mH.

Conclusion

In conclusion, PL8142NL fixed inductors are widely used in audio systems, power supplies, and circuit protection. Its high inductance capability and low parasitic capacitance make it a reliable component for many applications. It is also highly resistant to EMI interference and features a stable frequency range. Finally, its two different sizes make it suitable for a variety of applications.
