Fixed inductors, also known as coils, chokes, inductors, and filters, are components used in electronic circuits to induce an electromagnetic field when energized. The electromagnetic field created can be used for different purposes, such as creating a phase shift in an AC or DC signal, tuning the frequency of an electronic signal, or controlling current. The PL9216T is a low-cost, fixed-inductance surface-mount inductor application. In this article, we’ll discuss its application field and working principle.

Application Field

The PL9216T fixed inductors are primarily used in radio-frequency (RF) and microwave communications applications, where they can function as filters, inductors, and chokes. They can also be used in switching power supplies for various products. Their current ratings, low parasitic capacitance, and small size make them ideal for wireless communications systems, including WiFi and cellular networks.

The PL9216T inductors come in surface-mount packages and are suitable for applications requiring high power handling, stable inductance over temperature, and low parasitic capacitance. They are available in a variety of sizes and shapes, so manufacturers can easily customize their inductors to suit their specific application requirements. They also feature an optimally low impedance, which makes them attractive for use in high frequency applications.

Working Principle

In its simplest form, an inductor is a device comprised of an ‘inductor winding’ – typically wrapped around a ferromagnetic core – which stores energy in the form of an electromagnetic field. As the amount of current flowing through the winding increases, so does the amount of energy stored in the electromagnetic field of the inductor. This energy is later released back into the circuit, when the current decreases.

The PL9216T fixed inductors’ performance relies on the physical characteristics of its winding, its core material, and the amount of current flowing through it. The increase in current determines the amount of energy that is stored in the inductors field, which is then released back into the circuit. The amount of energy that is released can be manipulated by carefully selecting the number of windings, the core material, and the current used. By doing this, designers can fine tune the frequency of the energy output and its inductance.

Conclusion

The PL9216T fixed inductor is a highly capable device that offers reliable performance in the field of radio-frequency and microwave communications. It features an optimally low impedance and can be used in both surface-mount and leaded packages. Its magnetic core and winding can be used to adjust its inductance and frequency properties, allowing for greater control in applications that demand precise tuning. With its small size and high current ratings, the PL9216T is well-suited for manufacturers who require an efficient, easy-to-use inductor solution in their products.
