Fixed inductors are components designed to ensure a specific inductance in an electrical circuit. The ELJ - RE8N2JF2, manufactured by Panasonic, is a commonly applied fixed inductor used in various types of applications, such as power supplies, power converters, motor control circuits, and general signal processing.

The ELJ - RE8N2JF2 is a sealed construction fixed inductor with its main feature being its ability to provide excellent inductance with low electrical losses. The inductance values range from 0.56 μhenries to 10μhenries and the rated operating temperature is equal to + 125°C.

This fixed inductor consists of a copper coil wound around a ferrite core. The electrical properties of the ELJ - RE8N2JF2 are determined by its core material, and the design of the winding. Normally, the tolerance of inductance is ± 5%.

The ELJ - RE8N2JF2 plays an important role in a variety of applications, including voltage regulators, switching power supplies, and motor control applications. It is also used in circuits where the inductor is subjected to a considerable amount of applied current, as it provides good efficiency and stable performance. Additionally, due to its low electrical losses, it is commonly used in power supply circuits where a high power output is required.

The working principle of the ELJ - RE8N2JF2 is based on Faraday’s law of induction. When an alternating current passes through a coil, it creates a changing magnetic field which induces an electromotive force (EMF) in the coil. This EMF, which is proportional to the inductance of the coil, is then applied to the load. This process is known as self-induction.

The core material and the design of the winding of the ELJ - RE8N2JF2 affects the inductance of the coil. The core material is important because it provides the necessary magnetic permeability to achieve the required inductance. The design of the winding determines the value of the inductance generated by the coil. Generally, a higher number of windings or a larger overall coil size increases the inductance value.

Furthermore, as the rate of current passing through the coil increases, the inductance of the coil decreases. This phenomenon is known as self-heating, and its effects on the performance of the ELJ - RE8N2JF2 must be considered. To prevent self-heating, the maximum current passing through the inductor should not exceed a certain limit.

In conclusion, the ELJ - RE8N2JF2 is a widely used fixed inductor which can be applied in applications ranging from power conversion to motor control. Its ability to provide low electrical losses and excellent inductance makes it suitable for these applications. Additionally, its working principle is based on Faraday’s law of induction.
