Fixed inductors, such as the B82468A4222M, are used to store electric charges and are vital components in electronic circuits. Typically, they consist of a conductive coil wound around a ferromagnetic core, but variations can also be found in many applications. In many circuits, the inductor is said to be protected by the capacitance that it carries, and the behavior of the charge in the inductor can be studied in detail.

The B82468A4222M in particular is a high-power, high-current inductor designed to meet the needs of a wide range of applications. Its features include a low DCR of only 0.26 Ω, a high inductance of 220 μH, and a low core saturation current of up to 10A. Its structure also boasts a halogen-free glass encapsulation and high dielectric strength, making it suitable for various rugged environmental applications.

As for the working principle of the B82468A4222M, it relies on the inductance property of an electric current. When electrical current is passed through the winding of the coil surrounding the ferromagnetic core, the core acts as an electromagnet. This causes an opposing current to be induced in the core, leading to a self-induced voltage in the winding. The magnitude of this voltage depends on the inductance of the inductor, and this is what we refer to as the back EMF.

When the back EMF generated by the B82468A4222M is of an appropriate magnitude, it can react upon a current passing through the inductor and cause that current to decrease. Thus, the inductor is said to be a limited source of energy, as it “induces” foreign energy and uses it to limit the flow of current. This effect is what enables the B82468A4222M to be used in a wide variety of circuits and applications.

The B822468A4222M has found application in an array of electronic circuits and devices. For example, it can be used in power circuits such as DC/DC converters and in high power audio amplifiers. It is also frequently used in switching power supplies, resonant circuitry applications, and device noise reduction. Additionally, it is a great fit for (EMI) radio frequency interference radiation applications.

In conclusion, the B82468A4222M can be considered a fixed inductor. It features a conductive and ferromagnetic core coil, a low DCR, and a high inductance of 220 μH. It is designed to withstand harsh environmental conditions and is also suitable for a variety of circuits, including high power audio amplifiers, EMI noise reduction, and DC/DC converters.
