Fixed inductors, also known as chokes and coils, are energy storage components that can store energy within an inductor when an electric current is applied to it. Generally, they are categorized into three main types, namely, the air-core, ferrite-core and toroidal inductors. Their primary job is to “choke” various frequencies of electrons in an alternating current (AC) circuit, in order to reduce radio-frequency interference. Moreover, they can also be used as tuning elements in various electronic equipment.

The 84103C is a type of high-performance, fixed inductor specifically designed for use in high-volume, cost-sensitive commercial and industrial applications. It features a wind-through design, where the inductive element is wound around a ferrite core, thereby giving it a greater resistance to magnetic flux saturation. This results in a higher inductance value, making it perfect for use in high-frequency switching power applications. Moreover, it has a metal slug that absorbs RF energy, resulting in improved RF noise suppression.

The 84103C has a working principle wherein the applied current generates a magnetic field around the core. This magnetic field, in turn, induces a current in the inductor’s internal coil, producing an AC voltage. Based on the current flow and the number of turns in the coil, the voltage generated will be proportional to the frequency of the applied current. This allows the 84103C to be used in applications such as power line filtering, grounding and signal conditioning.

Additionally, the 84103C has various other features, such as a low DC resistance and a self-resonant frequency that is below 150MHz. This allows the components to operate at very high frequencies, while staying within the specified tolerances. Furthermore, the 84103C also features a wide operating temperature range of -40 to 85°C, making it an ideal choice for use in industrial environments.

In conclusion, the 84103C is a high-performance fixed inductor specifically designed for high-volume, cost-sensitive commercial and industrial applications. It has a unique wind-through design and metal slug for better RF noise suppression and higher inductance value. Its working principle is such that it “chokes” various frequencies of electrons in an alternating current circuit, allowing it to be used in a variety of applications. Furthermore, it also has the added benefit of a wide operating temperature range, making it ideal for use in harsh environments.
