The fixed inductor 4922R-03L and its application field and working principle

Fixed inductors are basic passive components used in electronics circuits which exhibit an inductance that is unchanging over the range of frequencies of their intended application. They are widely used as components in radio frequency and switching circuits, as they can store energy in the form of a magnetic field and serve a variety of purposes. The 4922R-03L is a fixed inductor manufactured by Pulse Electronics. This article will discuss the application field and working principle of the 4922R-03L.

Applications

The 4922R-03L is a small, high reliability, surface mount inductor designed for applications in harsh environmental conditions. It features silver over nickel-plated copper terminals to increase corrosion resistance and offers excellent mechanical and moisture resistance. Its high efficiency and low profile make it ideal for use in power supplies, voltage converters, and other power conversion applications. The 4922R-03L is suitable for automotive, industrial, and military applications and is ideal for use in mobile equipment, automotive applications, aircraft, and other harsh environments.

Working Principle

The 4922R-03L utilizes the principle of inductance in order to store energy in the form of a magnetic field. Inductance is the phenomena in which an electrical current is induced in a conductor by a varying magnetic field. The core of the inductor is typically made from a ferromagnetic material, such as iron or an alloy, surrounded by a tightly wound coil of copper wire. When an alternating current is applied to the coil, it creates a magnetic field in the core material. This in turn induces a current in the coil and produces an opposing electromagnetic field which resists the application of the alternating current.This opposing electromagnetic field functions to “store” the energy produced by the application of the alternating current and prevents it from dissipating. This stored energy can then be used to supply current to an electrical circuit. The strength of the inductor is determined by the number of turns in the coil and the material used for the core and is measured in henrys.

Conclusion

The 4922R-03L is a high reliability, surface mount inductor which is ideal for use in automotive, industrial, and military applications in harsh environments. It utilizes the principle of inductance to store energy in a magnetic field and is capable of resisting the application of an alternating current. Its high efficiency and low profile make it an attractive choice for power supplies, voltage conversion, and other power conversion applications.
