Fixed inductors are electrical devices that are designed to store electrical energy and control the current through the inductor. The ELC-18E471L is a fixed inductor that has a wide range of applications and operating principles.

In general, a fixed inductor is an electrical component that is designed with a fixed coil and consists of enameled copper or aluminum wire wrapped around a ferromagnetic core. The inductance of a fixed inductor is determined by the amount of wire used, the number of turns in the coil, and the geometry of the ferromagnetic core. The core material, air gap between the windings, and the type of insulation all contribute to the inductance of the inductor. The type of materials and designs used in fixed inductors are optimized to optimize inductance and minimize losses.

The ELC-18E471Lis a fixed inductor that consists of an enameled copper wire wound around a ferrite core. This inductor has an inductance of 18.0μH at 20 kHz of applied frequency and 5 mA of excitation current. It has a 2mil winding and features a single rectangularly-shaped ferrite core to support an electrical field of up to 20kHz. This inductor is rated for temperature ranges between -40⁰C and 85⁰C. It features RoHS compliance, lead-free construction, and is UL listed for safety.

The working of a fixed inductor is determined by the capacitance and the mutual inductance between the coils. The capacitance, also known as the parasitic capacitance, is determined by the amount of space between the windings as well as the type of insulation material used. The mutual inductance is determined by the magnetic field produced by the core material and the number of turns in the coil. According to Faraday\'s law, when an alternating current passes through an inductor, an opposing electromotive force is created and this opposing EMF opposes the current flow. This opposing EMF is what determines the power factor, the voltage drop, and the power loss in a fixed inductor.

The ELC-18E471L is a fixed inductor with a wide range of applications. It is widely used in transmission and distribution networks, power supply lines, receivers, and other electronic circuits.
