Fixed Inductors

Fixed inductors are types of passive electrical components that exhibit inductance, producing a magnetic field when conducting current. They are used to store energy in the form of magnetic fields and to provide a path for current in circuits. Fixed inductors are typically found in various power electronics applications. One example is the ELJ-FA150JF, a fixed inductor designed for filter applications in wide variety of electronic circuits.

Application Field

The ELJ-FA150JF is a fixed inductor designed for filter applications, such as power supplies, audio amplifiers, and TV sets. The inductor is constructed with electromagnetic coils wrapped around toroidal ferrite cores. This generates a high inductance, low-ESR, self-healing filter network structure which provides an optimal operating environment for electronic circuits. The ELJ-FA150JF also features a very high self-resonance frequency, which helps to reduce the size of physical filter components without sacrificing circuit performance.

Working Principle

The working principle of the ELJ-FA150JF inductor is based on Faraday’s law of induction. This law states that a changing magnetic field creates an electric current. In the case of the ELJ-FA150JF, the inductor is composed of two components – the ferrite core and the wire-wound coil. When a current is supplied to the coil, amagnetic field is generated around the ferrite core. This field has an effect on the electrons in the circuit, creating the induced current.

In order to increase the magnitude of this induced current, the number of turns in the coil can be increased, resulting in a higher inductance value. Increasing inductance helps to reduce voltage ripple and noise in the circuit, which is why it is commonly used in filter applications. The ELJ-FA150JF includes an embedded capacitor which provides additional resonance suppression in high-frequency circuits.

Conclusion

Fixed inductors like the ELJ-FA150JF are important components in various electronics circuits, providing improved performance by reducing voltage ripple and noise. By leveraging Faraday’s law of induction, the inductor generates an induced current to provide optimal operating conditions for circuits. The ELJ-FA150JF also features a self-resonance frequency, embedded capacitor, and high inductance, eliminating the need for a physical filter components and delivering improved performance without sacrificing circuit size or performance.
