Fixed Inductors

Inductors are basic components found in most electronic devices. They exhibit the ability to store energy in the form of an inductance, hence the name, and are available in a range of fixed configurations. ELJ-RE2N7DFA is a type of fixed inductor. This article looks at the application field and working principles of ELJ-RE2N7DFA.

Application Field

ELJ-RE2N7DFA inductors are primarily used for high-frequency applications. Being able to maintain performance with low parasitic elements, they are an ideal choice for radio frequency (RF) circuits. They are particularly used for voltage tunable inductors, LC filters, and to reduce high-frequency noise. They are also used in audio systems in order to isolate ground loops.

Working Principle

The core of an ELJ-RE2N7DFA inductor is made up of ferromagnetic materials, such as iron-silicon powder and ferrite, which are the foundation of an inductor. The inductance of the ELJ-RE2N7DFA is determined by the shape of the core and the number of winding turns, with a higher number of turns resulting in increased inductance. They are also able to dissipate the heat generated during operation due to their open air core. This allows for higher current density.

The inductance of the ELJ-RE2N7DFA inductor can further be increased or decreased by adding or removing turns, respectively. This is referred to as “turns ratio adjustment” and allows for the inductor to be tuned to different frequencies. This also known as “tunability”.

Additionally, they are able to minimize magnetic losses, due to their open air core design. This is a prominent advantage of ELJ-RE2N7DFA inductors over conventional inductors and transformers. The core material used in these inductors is capable of operating at a wide range of frequencies, enabling them to be used in high frequency applications.

Conclusion

To conclude, ELJ-RE2N7DFA inductors are a type of fixed inductor used for high-frequency applications. The inductance of this type of inductor is determined by the number of winding turns and shape of the core. The current density can be increased due to open air core design. Use of ferromagnetic materials, such as iron-silicon powder and ferrite, allow for these inductors to operate at a wide range of frequencies. The inductance further can also be tuned by increasing or decreasing the number of turns, which is referred to as "turns ratio adjustment". This unique feature of ELJ-RE2N7DFA inductors makes them an ideal choice for RF circuits.
