Introduction to Fixed Inductors

Fixed inductors are electronic components consisting of a coil of wire wrapped around a core, usually a ferromagnetic material like iron. In general, inductors are used in electric circuits to store energy in the form of a magnetic field, to control current flow, and to moderate voltage fluctuations. They are used in a wide range of applications, including electronics, telecommunications, automotive, military, aerospace, power supplies, computing, and medical sectors.

VLS5045EX-1R5N Application Field and Working Principle

The VLS5045EX-1R5N is a high frequency surface mount inductor from diode-centric. It is widely used for high-frequency switching applications in mobile devices, such as LO, RF, PA, battery charger & DC-DC stages in mobile phones, GPS receivers, etc. It is also suitable for any application that requires a high current inductor.

The VLS5045EX-1R5N has a low profile of only 1.3mm in height. It is an inductor with a high current rating of 10A, a high Q value of 28, and an operating temperature range of -40°C to +130°C. These features make it ideal for use in high-efficiency applications with high frequency operation.

The working principle of the VLS5045EX-1R5N is based on Faraday’s law of induction, which states that the induced electromotive force (emf) in a closed loop equals the time rate of change of the magnetic flux through the loop. In simple terms, when an electrical current is applied to a wire coil it induces a magnetic field, which in turn induces an electromotive force in the coil. This electromotive force is used to power electrical circuits.

The VLS5045EX-1R5N is designed with several layers of heat shield insulation material that help protect the inductor from short circuits and enhance stability. The core is wound with a single layer of copper wire that is insulated with a polyester varnish. The core is then encapsulated in epoxy resin to provide additional insulation. This design makes the VLS5045EX-1R5N extremely reliable and efficient in terms of inductance, current, and frequency.

Conclusion

The VLS5045EX-1R5N from diode-centric is a highly efficient and reliable fixed inductor, suitable for use in a wide range of high frequency and high power applications. Its operating temperature range of -40°C to +130°C makes it suitable for challenging environments and its low profile of only 1.3mm means it can be used in space-constrained applications. Its robust construction and efficient working principle based on Faraday’s law of induction make it a reliable, cost-effective solution for power applications.
