ELJ-ND18NJF Inductors, Coils, Chokes

Fixed inductors are passive electronic components used in a variety of electronic circuits as inductors. The ELJ-ND18NJF is one such type of inductor. This fixed inductor component is mainly used in noise canceling circuits, PWM applications, and voltage regulation circuits. The ELJ-ND18NJF is capable of withstanding a wide range of temperatures, from -40°C to +105°C, and is made from aluminum-electrolytic polyester material.

The ELJ-ND18NJF has a rated inductance of 1.8mH, a rated current of 380mA, and a rated voltage of 20V. It also features a self-resonant frequency of 100MHz. The inductor is designed to provide a high frequency signal path in circuits, allowing high voltage and current measurements with minimal distortion of the signal. The inductor can also be used in high power circuits by providing a stable operating current as well as a low resistance connection.

In terms of its working principle, the fixed inductor works by inducing a voltage field in the conductors when a varying current passes through it. This voltage produces a self-induced magnetic field, creating a countervoltage that opposes the voltage across the inductor. This process is referred to as electromotive force, and this is what causes the inductor to act as an ac resistor.

The ELJ-ND18NJF can also be used in variable frequency circuits, as it can be tuned to different frequencies. This is due to the fact that the inductance of the inductor is dependent on the total number of turns of its coils; by increasing the number of turns of the coil, the inductance is increased, and vice-versa. This allows the inductor to be tuned to different frequencies.

All in all, the ELJ-ND18NJF is a reliable fixed inductor that can be used in many applications, from PWM circuits to voltage regulators. With its ability to withstand high temperatures and a wide range of frequencies, this inductor is an ideal choice for various power-related applications.
