ELJ-NDR39JF Inductors, Coils, Chokes

Fixed inductors are an essential component of most electronics assembly projects. The ELJ-NDR39JF is a new high-grade fixed inductor designed to provide superior performance in a range of commercial, industrial and medical applications. This article will provide an overview of the ELJ-NDR39JF’s application field and its working principle.

The ELJ-NDR39JF is a high-frequency, compact fixed inductor that can be used in a range of power and signal applications. It is suitable for both AC and DC applications and is available in two sizes; 12.5mm and 14.5 mm. The ELJ-NDR39JF has a low DC resistance of 0.022 ohms, a high-frequency inductance of 20mH, and a self-resonant frequency of 275MHz. The unit also features a metal alloy core, which provides excellent heat dissipation and reduces EMI radiation.

The ELJ-NDR39JF can be used for a variety of applications, including power supplies, signal conditioning circuits, audio filters, DC-DC converters, voltage protection circuits, and RF transmission systems. The device is also well-suited for designing inductors for PWM converters, motor drives, switched mode power supply, signal processing circuits and other control systems. The device is also useful in power-line communication circuits.

The core of the ELJ-NDR39JF is made of a special magnetic alloy that helps the inductor to dissipate heat quickly and to maintain its stable operation over a wide temperature range. The inductor also has a low total harmonic distortion of 0.15%, which helps to reduce the interference levels generated by the inductor. The device also has a high current carrying capability, up to 20A, which makes it suitable for various high-current applications.

The working principle of the ELJ-NDR39JF is based on Faraday\'s law of induction. When an AC or DC signal is passed through the device, the magnetic field created by the signals induces a current in the coils of the inductor. The size of the induced current is proportional to the frequency and intensity of the signal. The device works by storing the a certain amount of energy in its field and releasing it when the field reaches a certain threshold.

The ELJ-NDR39JF is a high-performance, reliable and cost-effective inductor that can be used in a variety of applications. Its metal alloy core provides excellent heat dissipation and its low DC resistance and high frequency inductance make it suitable for high-frequency applications. By understanding its application field and its working principle, engineers and electronics hobbyists can easily select and use the device for their projects.
