Fixed Inductors: 4648-RC Application Field and Working Principle

Fixed inductors are physical components used to maintain electrical currents and voltages in an electric circuit. A 4648-RC fixed inductor is a type of device used in a variety of applications, particularly where high levels of power must be supplied reliably. This article will discuss the 4648-RC inductor, its application field, and its working principle.

Applications of 4648-RC Fixed Inductors

The 4648-RC inductor is commonly used in applications such as switched-mode power supplies, DC-DC converters, resonant converters, and soft-switching power converters. In addition, they can also be used to reduce noise levels by providing noise-filtering or by acting as a shunt inductor. The 4648-RC inductors are often chosen for these applications due to their high power rating, excellent thermal performance, and low core losses.

Construction of 4648-RC Fixed Inductors

A 4648-RC fixed inductor is typically constructed using a core composed of two materials, the main body being ferrite and the thin shell being a different material. This material combination improves the inductor’s heat resistance and ensures that it will not overheat during use. The two materials also provide greater magnetic saturation than pure ferrite cores, allowing the inductor to maintain a higher voltage rating.

Working Principle of 4648-RC Fixed Inductors

The working principle behind 4648-RC fixed inductors is simple. An alternating current (AC) is applied to an input terminal, and the inductor then stores this energy in its electromagnetic field, then releasing the stored energy when the current flow is reversed. This stored energy acts to sustain the current within the inductor, which reduces the losses that can occur in resistive components. This makes them invaluable for use in high power applications, as they are able to regulate the voltage levels more effectively with minimal power losses.

Conclusion

The 4648-RC fixed inductor is a useful component for use in a variety of applications, such as switched-mode power supplies, dc-dc converters, soft-switching converters, and noise-filtering. Its construction consists of a core made up of two materials, and its working principle involves the storage and release of energy to sustain the current and reduce losses. Together, these features make the 4648-RC inductor an effective solution for high-power applications.
