Fixed Inductors

ELC11D121F

Application Field

ELC11D121F fixed inductors are ideal for a wide range of applications including power supplies, DC-DC converters, switching regulator output filters, noise suppression, and EMI filters. They can also be used in low-pass, high-pass, and band-pass filters, which are important in radio equipment. With their high levels of performance, they are suitable for use in any application where small size and low current are important.

Working Principle

A fixed inductor works by creating a magnetic field when a current is passed through it. The magnetic field induces an electromotive force in the inductor, which opposes the flow of current. This opposition to current is referred to as inductance. The amount of inductance is determined by the number of windings, the material of the core, and the physical size of the inductor. The principal of an inductor follows a simple law, known as Faraday’s law, which states: "The rate of change of magnetic flux through a conductor is proportional to the current in the conductor." This law is the fundamental principle behind all types of inductors and explains how the changing magnetic field creates an opposition to current in the inductor, known as inductance. ELC11D121F fixed inductors are specifically designed to affect the current in a particular manner by creating a specific inductance. This is done by controlling the number of windings, the material of the core, and the physical size of the inductor. By controlling these three parameters, ELC11D121F fixed inductors can be made to create the desired inductance for any particular application.

Conclusion

ELC11D121F fixed inductors are ideal for a wide range of applications due to their high levels of performance. By controlling the number of windings, core material, and physical size of the inductor, the desired inductance can be obtained. This allows ELC11D121F fixed inductors to be used in a variety of applications, such as power supplies, DC-DC converters, switching regulators, low-pass, high-pass, and band-pass filters, noise suppression, and EMI filters.
