HF1008R-222K

Fixed inductors are a type of electrical inductor with a certain inductance value. An example of a fixed inductor is the HF1008R-222K. This inductor is a small, molded radial lead inductor used for general purpose applications.

The inductor is composed of a ferrite core and a coated copper wire. The ferrite core is an insulating material with a high magnetic permeability, while the coated copper wire is insulated and is the conductor of the inductor. The inductance value for this specific inductor is 100nH +/- 10%.

In its application field, the HF1008R-222K inductor is used for various types of general-purpose electronics, such as in radio sets, cellphones, and power supplies. It is designed to provide filtering, decoupling, and EMI suppression. It is also used in the design of low voltage dc/dc converters, and for voltage regulators. Its rated DC current is rated at 101 mA, and its rated DC resistance is 0.222 ohms.

The working principle of the HF1008R-222K inductor is based on the principle of electromagnetic induction. When a current passes through the inductor, it results in the generation of a magnetic field around the inductor. This magnetic field induces an opposing electromotive force in the inductor\'s windings, whose magnitude is directly proportional to the rate of change of current. This phenomenon is known as inductance, which is the main feature of any inductor.

Therefore, when changing current passes through the HF1008R-222K inductor, there will be an opposing electromotive force, which will then oppose the source current, resulting in a reduced current flow. In this way, the HF1008R-222K inductor acts as a filter, decoupling the source from the load, thus protecting the load from transient changes in the source.

In conclusion, the HF1008R-222K is a fixed inductor that is used for various types of general-purpose electronics. Its use helps protect the load from transient changes in the source, and it also helps reduce input and output interference in radio and audio circuits. Its design and rated parameters make it suitable for many types of general-purpose applications.
