Fixed Inductors

A fixed inductor is a two-terminal device that stores energy through its inductance. It is composed of one or more windings of insulated metal wire wound on a core material. The inductance of the component is determined by the size, shape, and winding of the core, along with materials used. The type of core material also plays an important role in deciding the inductance of the component.

The PL9205T is a medium size, adjustable inductor designed for use with frequency converters, switching power supplies, and rectifiers. It features a unique construction that utilizes a robust core material and split winding to provide reliable and consistent current carrying performance over a wide frequency range. Its adjustable design enables it to be tuned to the application\'s specific frequency needs, allowing for efficient operation and increased performance.

Application Field

The PL9205T is ideal for applications where load current can vary significantly. It can be used in switched mode power supplies, power converters, and rectifiers where an adjustable inductor allows for finer tuning of the output current. This makes it an ideal choice for a wide range of applications, such as automotive electronics, surge protection, and high frequency switching.

The PL9205T can also be used in other applications such as clock circuits, RF amplifiers, and pulse transformers. Due to its adjustable design, it can be used to tune the frequency of the circuit to the desired operating frequency. Additionally, it can be used in high frequency chokes and filters to reduce emissions and interference.

Working Principle

Like all inductors, the PL9205T works by creating a magnetic field in response to the flow of electric current. The core material, along with the number, shape, and size of the windings, determine the inductance of the component. When electric current flows through the coil, the magnetic field increases, inducing a back-EMF voltage that opposes the applied voltage. This relationship is known as Faraday’s Law of Induction.

The adjustable design of the PL9205T allows for fine tuning of the component’s inductance. This is achieved by varying the number and shape of the windings, and by changing the composition of the core material. By adjusting the number of windings and type of core material used, the inductance can be precisely tuned to meet the application’s specific needs.

Conclusion

The PL9205T fixed inductor features a unique adjustable design that enables it to be used in a wide range of applications, including switched-mode power supplies, frequency converters, and rectifiers. Its adjustable design allows for tuning of the inductance to match the application’s specific current and frequency requirements. This makes it an ideal choice for automotive, surge protection, high frequency switching, and RF amplifier applications.
