Fixed Inductors

The S4924-823J is a fixed inductor. It has been widely used in various fields, and this article will discuss the application field and working principle of the S4924-823J.

Application Field

The S4924-823J is most commonly used in power conversion circuits where large currents need to be controlled, such as AC/DC converters, DC/DC converters, and switching converters. They are also used in electromagnetic interference interference circuits, such as overvoltage protection in digital circuits. In addition, they are used for signal filtering purpose. Because of their ability to store and release large amounts of energy, they are used in filtering circuits for radiofrequency signals with high power.

Working Principle

The working principle of a fixed inductor is based on its effect on electrical and magnetic fields. An inductor consists of a coil of wire wound around a core, which helps concentrate and direct the magnetic field. When a current passes through the coil, it produces a magnetic field that stores energy. This stored energy is proportional to the current through the coil. When the current is cut off, the magnetic field begins to collapse releasing the stored energy. This release of energy is typically turned into an electrical current or voltage.

When a voltage is applied to an inductor, a large current flow is resisted. During this period, the inductor\'s coil stores energy in a magnetic field that builds up around the coil. As the voltage across the inductor increases, the current also increases until it reaches its maximum value. This maximum current is known as the saturation current. After this point, the inductor will continue to oppose any further increase in current, but the voltage across it will not increase further.

The value of the inductance for the S4924-823J is 8uH with tolerances of + 10% or - 20%. The rated current for the inductor is 2.7A. The S4924-823J is temperature rated between -40 to 85°C. It also complies with the UL94V-0 flame retardant.

In conclusion, the S4924-823J is a fixed inductor with a wide variety of applications. It has an inductance value of 8uH with a maximum rated current of 2.7A. It also complies with the UL94V-0 flame retardant and is temperature rated between -40 to 85°C. It is used in power conversion circuits, electromagnetic interference circuits, and signal filtering.
