Fixed inductors have been used in electronic circuits for decades and are constantly being re-imagined to fit the needs of new applications and device redesigns. A perfect example of this is the PA4025.361HL Inductor. Unlike regular inductors, this inductor has a ferrite core, which helps it provide higher inductance without having to increase its physical size. This makes it perfect for use in tight spaces, such as in cellular phones and other portable electronics.

Application Field

The PA4025.361HL is designed for use in RF modules and flat-panel displays. It provides good impedance matching in the DC and low-frequency regions, making it useful in filtering applications. Its high-frequency characteristics are also superior, offering excellent attenuation with a low core loss and relatively high efficiency. As a result, it is often used for broadband and high-frequency pull up/pull down applications.

Working Principle

Fixed inductors work through electromagnetic induction. A coil of insulated wire is wrapped around the core, generating an electromagnetic field as current passes through it. When an alternating current is applied, a magnetic field is produced that stores energy, resulting in a phase shift between the current and voltage waveforms. This effect is known as inductance and dictates the amount of current that a fixed inductor can provide over a given period.

The PA4025.361HL Inductor can handle high frequencies because of its low inductance core. The core consists of a ferrite material which enables it to operate at frequencies up to 4GHz without sacrificing the level of inductance. Consequently, the PA4025.361HL is able to provide high impedance matching throughout the band of frequencies it is designed for.

Overall, the PA4025.361HL Inductor is a highly efficient and reliable device. Its low core loss allows it to operate at frequencies up to 4GHz, making it ideal for use in portable devices. At the same time, its high inductance allows it to be used in high-frequency pull up/pull down applications and RF modules along with flat-panel displays.
