Fixed Inductors

Fixed inductors are electronic components consisting of a conductor such as a wire, usually wound into a coil, that stores electrical energy in a magnetic field when an electric current flows through it. They are used in a variety of electronic circuits, such as power supply circuits and amplifiers, and can provide a wide range of different inductance values. The most common type of fixed inductor is the air core inductor, which uses air as a core. Other types include ferrite core inductors, which use a ferrite material as a core, and the shielded inductor, which uses a metal shield or enclosure for additional protection from external magnetic fields. The ELJ-FJR27GF2 is an example of a fixed inductor.

ELJ-FJR27GF2 Application Field and Working Principle

The ELJ-FJR27GF2 is a high-frequency shielded inductor, with shielded construction that allows for greater shielding efficiency over air core inductors. The ELJ-FJR27GF2 is designed for applications such as power transmission lines, power supply circuits, and high frequency amplifiers. The construction of the ELJ-FJR27GF2 consists of a wound wire coil with a metal shield to provide greater shielding from external magnetic fields. The metal shield also helps minimize the capacitive affects of circuit components, allowing for higher frequency operation with less distortion. The coil is typically formed from a single insulated wire with a core (air, ferrite, etc.) in the center, which helps concentrate the electromagnetic field for greater inductance.

The working principle of the ELJ-FJR27GF2 is based on the principle of electromagnetic induction. When electric current passes through the inductor, a magnetic field is created, which induces an electric current in nearby conducting objects. This induced electric current produces a back-EMF, which opposes the current passing through the inductor, resulting in an effect known as inductive reactance. This reactance opposes and reduces the original current, and limits its rate of change (known as inductance). The higher the frequency of the applied current, the greater the inductive reactance.

The inductance of the ELJ-FJR27GF2 can be adjusted by changing the number of turns in the coil, or by changing the size and shape of the core material used. Adjusting the inductance of the ELJ-FJR27GF2 is important, as it affects the electronic characteristics of the circuit such as its frequency response and distortion characteristics. The ELJ-FJR27GF2 also has a high self-resonant frequency, which means that it can be used in high-frequency applications without suffering from excessive losses.

The ELJ-FJR27GF2 is a high-performance, cost-effective inductor that can be used in a wide range of electronic applications. It has a wide inductance range, high self-resonant frequency, and shielded construction, which allows it to provide efficient protection from external magnetic fields. Its ease of use and customizable design make it an ideal solution for a variety of different applications.
