Fixed inductors are small electrical components made up of a coil wrapped around an iron core or semiconductor core. They are used to store and direct electrical energy, and are frequently seen in circuit boards in various gadgets.The ELC-3FN2R7N is a typical example of a fixed inductor. It is available in various package sizes and lengths, ranging from 2.0mm to 15.0mm, and is usually made up of silver-plated copper wire and an insulated ferrite core.

In terms of application, fixed inductors such as the ELC-3FN2R7N are mainly used in switch mode power supplies, DC-DC converters, and high frequency filters. Additionally, they can be employed in common mode feedback circuits, customer power conversion systems, and time-delay circuits. Their primary purpose is to direct the flow of current and voltage to ensure electrical charge and energy is stored.

As for its working principle, the ELC-3FN2R7N operates as a high frequency filter by blocking high frequency interference signals and allowing low frequency signals to pass. Its ferrite core can act like an inductor by preventing current from flowing in one direction. When current flows through the inductor, a magnetic field is generated – this field opposes the current, thus creating an opposing voltage. This voltage impedes current flow, and helps maintain a consistent current and voltage.

In summation, fixed inductors, like the ELC-3FN2R7N, are small electrical components made up of a coil wrapped around an insulated, ferrite core. They are often used in switch mode power supplies, DC-DC converters, and high frequency filters to store and direct electrical energy, and can act like an inductor by preventing current from flowing in one direction and generating a magnetic field.
