Fixed Inductors

Fixed Inductors are static components that store inductance within a magnetic field. Specifically, the S1812R-105G is a wire-wound non-polarized inductor typically used for AC and DC signal filtering and line protection applications. It offers low loss performance and a high thermal resistance for improved power handling capabilities.

Application Field

Typical applications for the S1812R-105G include: higher-frequency switching power supplies, DC/DC converters, LC filters, buck and boost converters, line impedance stabilization for various measurement and control equipment, DC/AC inverters, and automotive applications.

Construction

This specific inductor features a ferrite rod core, and its construction allows for strong inductance and low current consumption. The S1812R-105G utilizes an UL 94V-1 grade flame retardant plastic body and copper wire, which helps with heat dissipation while minimizing the size of the inductor.

Working Principle

The inductor utilizes a core made from ferrite and enameled copper wire wound together. When electrical current passes through the winding, it creates an electromagnetic field within the core of the ferrite, which, in turn, stores energy. This energy can then be released, as and when required, causing a voltage to rise and fall within the component. This process is known as inductance, and allows for the application to achieve specific regulation or filtering of AC/DC signals.
