Fixed inductors are electromechanical components used to store and release electrical energy in electronic circuits. The ELJ-NDR18JF is a fixed inductor that is suitable for applications in a variety of electronic circuits. This article will explain its application field and working principle.

Applications for ELJ-NDR18JF

The ELJ-NDR18JF is commonly used in power conversion regulation systems, such as in switchers and inverters. It is also used in various electronic devices, including lighting, inverters, motor controllers, and automotive electronics. The inductor can also be found in white goods, such as digital display devices and air conditioners. Additionally, the inductor can be used in audio/video products and semiconductor devices.

The ELJ-NDR18JF is designed for use in low-side switching circuits, where the inductor is connected from the power source to the switching device. Its compact size makes it suitable for high-density printed circuit boards. The inductor has an inductance value of 18µH, with an inductance tolerance of ±20%, and a rated current of 1.5A.

Working Principle of ELJ-NDR18JF

The ELJ-NDR18JF works by converting electrical energy into magnetic energy and then releasing it when required. This is achieved by the movement of the wire within the inductor. When the wire is moving, it creates a magnetic field that stores the electrical energy. The stored energy is then released when the current flow is stopped or reversed.

The inductor consists of a series of wire segments, insulated from each other by a thin core material. When current flows in a single direction, the wire segments induce a magnetic field in the core material, which stores the energy. When the current flow is reversed, the stored energy is released as the magnetic field collapses.

The inductance of the ELJ-NDR18JF is determined by the geometrical arrangement of the wire segments. The longer the coil, the higher the inductance value. The inductor can also be designed to have an adjustable inductance, allowing the user to adjust the frequency and current levels when used in different applications.

Advantages of ELJ-NDR18JF

The ELJ-NDR18JF provides significant advantages over other types of inductors. It has a small size, which makes it ideal for high-density boards. It is also highly reliable and resistant to vibration and shock. Its low external diode loss can help to improve switching efficiency. Finally, its adjustable inductance allows for customized frequency levels.

In addition to the above, the ELJ-NDR18JF has a higher energy rating than other types of inductors, making it suitable for applications with high current levels. It also has a wide operating range, making it suitable for a variety of applications. The inductor is also RoHS compliant, making it suitable for use in commercial and industrial applications.

Conclusion

The ELJ-NDR18JF is a fixed inductor that is suitable for a variety of electronic applications.
