A fixed inductor, also known as a non-variable inductor, is an electronic component that operates by storing energy in a magnetic field. Fixed inductors are inseparable components of circuits that transfer and regulate electrical energy. Depending on the application, inductors are classified in various ways, such as first-order, second-order, air-core, and ferrite-core. The ELC-18B103L fixed inductor is a type of non-variable inductor used in a wide variety of applications.

The ELC-18B103L is a low-profile inductor designed to be used in many low-power applications, such as mobile phones, laptop computers, and power supplies. It has two configurations, namely through-hole and surface mount, thus making it an excellent choice for a wide range of applications. The through-hole type features two pins that allow for easy mounting while the surface-mount type has four pins that allow for secure mounting onto a board. The ELC-18B103L has an impedance of 0.45mH, a rated current of 3A, and a very small size of 4.3mm x 6.3mm.

The ELC-18B103L works by converting alternating current (AC) to a steady current, thus providing the current needed for powering various components of the circuit where it is connected. It acts as an impedance buffer, meaning that it acts as a protection device that limits the current flow in the circuit, thus preventing circuit damage. Additionally, it absorbs and dissipates the variable electrical energy that usually accumulates in the circuit, thus preventing voltage spikes. Furthermore, as inductors, they act as electromagnets that create a magnetic field to store the electrical energy.

The ELC-18B103L is best used in power conversion circuit topology, particularly in flyback forward converters, SFX converters, multiphase converters, and buck/boost converters. In these circuit topologies, the ELC-18B103L helps ensure the stability of the power supply to the connected devices by providing an impedance buffer from the power source and limiting the amount of electrical power that passes through the circuit. The ELC-18B103L is also suitable for use in power management circuits, where it regulates the current supplied to the circuit components.

In conclusion, the ELC-18B103L fixed inductor is an ideal choice for countless low-power applications. It functions by converting alternating current to a steady current and providing an impedance buffer to protect electrical circuits. It is suitable for use in a wide range of circuit topologies, such as flyback forward converters, SFX converters, multiphase converters, and buck/boost converters. Additionally, it is best used in power conversion and management circuits.
