Fixed inductors, including the HF1008-221G, are used in range of applications requiring inductor solutions. They are used to store electrical energy and regulate currents within electronic components.

An inductor is an electronic component composed of a coil of wire wrapped around a core material. As an electric current is passed through the coil, a magnetic field is created and this field stores the energy. Inductors can act as filters, oscillators, and impedance matching components.

The HF1008-221G is a surface mounted inductor with a size of 10x8x3.2mm. It operates in a range of 20MHz to 90MHz with an inductance of 220maH. The coil construction includes 100 turns of 0.09 Alumina (AL) wire and a ferrite core. It also features a high Q value, which means it is able to store a large amount of energy. Additionally, the HF1008-221G has a low profile design, making it suitable for applications requiring higher density mounting.

The primary application for the HF1008-221G is for impedance matching in RF circuits. For example, it is often used in cellular phone antenna systems to match impedances between the antenna and the radio receiver. With its low profile design, the HF1008-221G is also ideal for applications where size is important, such as miniature radio transceivers.

The working principle of the HF1008-221G is similar to that of other inductors. When an alternating current is passed through the coil of the HF1008-221G, a changing magnetic field is created. This changing magnetic field creates an electric field, which, in turn, induces an electric current in the inductor. This current opposes the original current, creating a resistance in the circuit and limiting the current flow.

Fixed inductors such as the HF1008-221G are essential components in a wide range of electronic circuits and systems due to their ability to store and regulate current. They can be used for impedance matching and filtering applications as well as for low profile designs, making them an ideal choice for application where size is a factor.
