Fixed Inductors

Fixed inductors, commonly known as "chokes", are devices used to reduce the amount of alternating current (AC) that flows within a circuit. In their most basic form, they are simply a coil of wire that is wrapped around a core, though modern designs incorporate additional components such as magnets to improve the amount of inductance they create. In any case, a fixed inductor works by limiting how much AC electricity is able to pass through the circuit, and in doing so, maintain a desirable level of system stability within the circuit.

Among the many different types of fixed inductors available, the B82422T3390J000 is a popular high-performance surface-mount fixed inductor designed for applications in the automotive, telecommunications, broadcast, marine, base station, and defence industries.

The design of the B82422T3390J000 combines multiple features such as high inductance-to-volume ratio, low DC resistance, and a high-temperature UL 94V-0 approved plastic case with a metal cover to ensure maximum protection. The inductor itself comprises an iron-based core material surrounded by an electronically insulated winding. In order to ensure maximum compliance for a wide range of environmental and operating conditions, the design of the core material is specifically configured to offer optimizations in both electrical and thermal limits.

The working principle behind a fixed inductor is relatively straightforward. An AC voltage is applied to the inductor and is then induced into a magnetic field within the winding. As the magnetic field builds, so does the inductance, which in turn, restricts the amount of current that is allowed to flow through the circuit. The magnitude of the inductance created (and hence the amount of current the inductor is able to restrict) is determined by the number of windings used, as well as the inductor’s core material.

In terms of applications, the B82422T3390J000 is primarily used as a high-frequency filter, antenna coupling, or transformer in telecommunications systems, as well as an EMI filter for automotive applications. Due to its high inductance-to-volume ratio, the B82422T3390J000 can also be used as an EMI/RFI filter in power supplies and switching circuits.

In conclusion, the B82422T3390J000 is a high-performance, high-inductance fixed inductor designed for a wide range of applications in the automotive, telecommunications, broadcast, marine, base station, and defence industries. Its core material is designed to ensure maximum compliance for a variety of environmental and operating conditions, and its working principle is based on the fact that an AC voltage is applied to the inductor and is then induced into a magnetic field within the winding. As the magnetic field builds, the inductance also increases, which in turn, restricts the amount of current allowed to flow through the circuit.
