Fixed Inductors

Fixed inductors, also known as chokes, are passive components consisting of coiled metals (usually copper) that are designed to reduce/ limit the passage of alternating current (AC) signals. The most common type of fixed inductors is the ELJ-RG2N2DF. This type of inductor consists of two ends, both of which have a length of 5.03mm. On one end of the inductor is a plastic casing, while on the other a point-of-contact connection. Fixed inductors are commonly used in radio frequency circuits for the purpose of matching impedances, as well as to filter, decouple, smooth, and amplify signals.

ELJ-RG2N2DF Application Field and Working Principle

The ELJ-RG2N2DF is an excellent choice for a variety of applications, particularly those involving the reduction of high-frequency noise. With an inductance of 1.7nH and a self-resonant frequency of 45MHz, the ELJ-RG2N2DF is optimal for such uses. It is also used to match impedances in both AC power applications and radio frequency circuits.

The working principle of a fixed inductor is relatively simple. The device consists of two components, an inductopass and a capacitor. The inductopass is a coil of wire which is used to create a magnetic field when a current is applied to it. This field works to resist changes to the current, which is known as inductance. The capacitor is used to store energy coming from the inductor, while simultaneously allowing a leakage current. This current is what causes the inductor to reduce the amplitude of the current through it.

The ELJ-RG2N2DF is especially useful for applications where a high-frequency noise reduction is needed. While traditional capacitors may be used for this purpose, the ELJ-RG2N2DF is able to provide greater filtering capabilities due to its higher self-resonant frequency and inductance.

In summary, the ELJ-RG2N2DF is an excellent choice for a variety of applications, particularly those involving the reduction of high-frequency noise. The device is composed of two components, an inductopass and a capacitor, which work together to reduce the amplitude of the current passing through it. With its high self-resonant frequency and inductance, the ELJ-RG2N2DF is also ideal for applications involving the matching of impedances in AC power applications or radio frequency circuits.
