Fixed Inductors

Fixed inductors, most commonly of the wound-coil variety, are among the most common passive components in electronic circuits. The B82422T1184K000 series, in particular, is a surface-mount ceramic-bodied, shielded inductor that operates in the 300 kHz to 300 MHz range.

Application Field

Due to the wide frequency range and high Q of the B82422T1184K000 series, as well as its ability to handle large current without significant power dissipation, it is often used in various high frequency analogue circuits, in particular where filters and signal coupling are involved. It is particularly popular in applications such as RF communication systems, filtering, pulse transformer, high-frequency switching power supplies, clock signals, transceiver circuits, and high-frequency AC circuits.

Examples of such applications may include pulse power converters, RF receivers, and antenna applications. As this type of inductor has a consistent impedance over a wide range of frequencies, it is widely used in all kinds of signal processing circuits, such as filters and amplifiers. Moreover, it can be used in broadband power supplies to suppress high-frequency spikes, as well as for coupling and matching between stages, and has been found to be ideal for auto-detection and switching circuits.

Working Principle

The B82422T1184K000 series is a type of fixed inductor, meaning that its inductance remains constant over a wide range of frequencies. This is achieved by winding an insulated copper or other magnetic wire around a core of magnetic material, usually iron or a ferrite material. This combination of wire and magnetic core is what creates the inductive properties.

When an alternating current passes through the inductor, it creates an electromagnetic field that interacts with the magnetic material in the core. This induces an opposing current in the wire, and this is what gives rise to the property of inductance. The amount of inductance is determined by the number of turns of wire, the type of core material used, and the air gap in the core.

The B82422T1184K000 series inductors are shielded for better reliability and protection, as well as improved performance, and offer a wideband resonance peak range of 1 to 10 MHz. In addition, they feature a ceramic body construction which improves their performance and provides better heat management. The high Q, low DC resistance, and high inductance of these devices make them ideal for high-frequency applications.

In summary, the B82422T1184K000 series is a type of fixed inductor that offers a wide variety of potential applications in numerous analogue filters, amplifiers, and signal processing circuits. It is particularly suitable for high-frequency switching and auto-detection, as well as for providing high-impedance suppression in power supplies. With its ceramic body construction, shielded design, high Q, and wideband resonance peak range, the B82422T1184K000 series is an ideal choice for those in need of a fixed inductor for an application requiring high-frequency performance.
