Introduction of Fixed Inductors

Fixed inductors, also known as choke coils, are important components of power supplies and electronic circuits. They allow electrical current in one direction and act as voltage regulators. Commonly used in the electronics industry, these components can be found in almost every electrical device.

What are Fixed Inductors?

Fixed inductors are basically a coil of wire that carries electrical current when it is created with a specific number of turns and wrapped around a core made from either ferrite or iron. The currents are then passed through the coils, creating an alternating magnetic field. The field is responsible for the production of inductance. The greater the number of turns, the greater the inductance, which is measured in henries (H).

Types of Fixed Inductors

Fixed inductors come in a variety of sizes, shapes and materials. Common types include air core, iron core, laminated core, ferrite core, and multilayer inductors. Air core inductors use the air as its core material, while iron core inductors are wound around an iron core. Laminated core inductors are composed of laminated metal plates, and ferrite core inductors are wound with ferrite as its core material. Multilayer inductors are composed of multiple layers of metal films separated by a dielectric material, and are well-suited for high-frequency applications.

MS75087-1RU Application Field and Working Principle

The MS75087-1RU fixed inductor is an iron core inductor with a 1RU (43mm x 10mm x 8mm) radial leaded construction and winding with a ferrite core. The MS75087-1RU is designed for use in switching mode power supplies, LED lighting, telecommunications and other consumer products that require low profile solutions.The working principle of the MS75087-1RU induction depends on the principles of magnetic induction. The MS75087-1RU features a ferrite core surrounded by a wire winding. When an electrical current passes through the windings a magnetic field is created that induces a voltage drop across the windings. This is the effect of self-inductance. The self-inductance is measured in henries (H), which is a measurement of inductive reactance. The reactance means the opposition to the current flow by a reactive component.

Conclusion

Fixed inductors are essential components of power supplies and electronic circuits. Common types include air core, iron core, laminated core, ferrite core, and multilayer inductors. The MS75087-1RU fixed inductor is an iron core inductor with a 1RU radial leaded construction and winding with a ferrite core that is well-suited for high-frequency applications. Its working principle depends on the principles of magnetic induction, by inducing a voltage drop across the windings.
