Fixed inductors are widely used in various electrical and electronic circuits, and its application fields and working principles could vary upon the specific type of them. It is the purpose of this article to explain the application field and working principle of one specific fixed inductor, PA4340.153NLT.

At first, let us take a look at its application fields. Generally speaking, the PA4340.153NLT fixed inductor is specifically designed for use in high frequency circuits or board-level products involving pulsed signal with large amplitude. Its ability to provide high quality, high volume, and low cost inductor components, add up to its wide application in many different fields, such as communication system, radar system, and so on. It can offer great performance in operating frequencies up to 500MHz.

Now, let us turn to its working principle. Just like any other inductor, it has a core material consisting of two parts, a core material and a coil. It works through a process called inductance, which is the use of eddy current in the coil material to create a magnetic field to oppose the change in the current. This is what is known as the “inductance effect” and when the current stops flowing, a voltage spike is generated. This is the reason this type of inductor often used in high frequency applications.

When the current is flowing, a magnetic field is generated in the coil, which induces a counter-current in the core material, effectively cancelling the applied current. This is known as the “counter-inductance effect”. In other words, it works by orienting the core material in a way that it opposes the flow of current, which in turn reduces the impedance and allows for attenuation of signals.

Lastly, the PA4340.153NLT fixed inductor has an additional benefit in that it has far fewer cores compared to some other types, which makes it far more efficient at dissipating heat. This is essential in high frequency circuit, as it does not heat up quickly, thereby providing a more reliable performance with reduced risk of damages.

To sum up, PA4340.153NLT is a type of fixed inductor, specifically for use in high frequency circuits or board-level products where pulsed signals with large amplitude are required. It has several advantages, such as its ability to provide high quality, high volume, and low cost inductor components, and its ability to operate frequencies up to 500MHz. It also has a “counter-inductance effect” and the advantage of far fewer cores compared to other types, which makes it far more efficient at dissipating heat.
