<h2>Fixed Inductors</h2> <p>Fixed inductors are an essential part of most electrical systems. They are electronic components that store electrical energy in a magnetic field and then release it over time. Fixed inductors are composed of two basic components: a wire coil and a ferromagnetic core. The wire coil is the source of the energy, and the ferromagnetic core helps to concentrate the magnetic field.</p><h3>SCRH105R-821 Application Field and Working Principle</h3> <p>The SCRH105R-821 fixed inductors from Sumida are suitable for various application fields like power supplies and control equipment. This inductor can reach an inductance of 4.7mH when the rated current is 0.50A. It can also operate within a wide temperature range, from -25°C to +85°C.</p><p>In terms of working principle, the SCRH105R-821 fixed inductor basically involves two steps. First, when electric current flows through the wire coil, a magnetic field is created which generates a voltage across the coil. This voltage induces an electric current in the coil, and it is stored in the form of energy in the magnetic field. Second, upon the interruption of the electric current, the stored energy is gradually released. This release of energy generates a voltage across the coil which induces a current in the coil, with the same direction as the original flow of electric current.</p><p>The SCRH105R-821 fixed inductor has an outer layer of metal to protect the wire coil from any external damage and is also flame retardant as per UL94V-0.</p><p>This inductor is also equipped with a built-in protection circuit to prevent damage from over-voltage and short-circuit faults. Furthermore, its high temperature and operating characteristics make it suitable for many high-temperature applications in harsh environments.</p>
