Fixed Inductors: 4922R-48K Application Field and Working Principle

Inductors are electrical components which exhibit inductance, and fixed inductors are electrical components with a fixed inductance. The 4922R-48K is a fixed inductor with characteristics and features designed for high power applications in industrial, medical, and automotive industries. It is suitable for use in various circuits, such as power supplies, motor drives, power factor correction, and electronic loads. In this article, we’ll explore the application field of 4922R-48K and its working principle.

Applications of the 4922R-48K

The 4922R-48K is a high-power inductor with a current rating of up to 48A and a voltage rating of up to 160V. This makes it suitable for many high power applications. It is widely used in switched-mode power supplies (SMPSs), motor drives, power factor correction (PFC) circuits, and electronic loads. In addition, its robust construction and high power efficiency make it a suitable choice for industrial and automotive applications.The 4922R-48K is also suitable for use in high-efficiency devices, such as computers, servers, and other equipment, thanks to its low resistance and high frequency response. Furthermore, its high surge current capacity and high temperature operation make it suitable for high current electric pumping systems, off-line power converters, and multi-stage filters.

Working Principle of the 4922R-48K

The working principle of the 4922R-48K is based on Faraday’s Law of induction. This states that when a conductor, such as a wire, is exposed to a changing magnetic field, electric current will be induced in the conductor. The induced current is known as the counter electromotive force, or counter EMF.The 4922R-48K works on the same principle. It is constructed from a core material and a wound copper coil, which act together to induce a counter EMF. When a current is applied to the 4922R-48K, a magnetic field is generated by the windings. This induces a counter EMF in the windings, which opposes the current flowing through the 4922R-48K. This opposition produces a force which resists the flow of current, resulting in a decrease in the applied current and an increase in the output voltage.

Conclusion

The 4922R-48K is a high power fixed inductor which is suitable for various high-power applications, from motor drives to PFC circuits. Its high efficiency, low resistance, and high frequency response make it an ideal choice for a range of electronics applications. Its working principle is based on Faraday’s Law of induction, where a changing magnetic field induces a counter EMF in a copper coil, which opposes the applied current and produces a force that reduces the current flow and increases the output voltage.
