Introduction

Fixed inductors are passive electronic components used to store electrical energy in a magnetic field. They are also known as coils, chokes, or reactors. Fixed inductors come in a wide variety of shapes, sizes, and operation frequencies. The VLS3010T-4R7MR80 is one of them. It is a high-frequency, shielded, ferrite core, axially leaded Inductor, with a maximum DC current of 4.7A and a rated DC resistance of 0.008 Ohm.

Application Field

Fixed inductors are primarily used to store electric energy temporarily, reduce EMI or RFI noise, and filter current or voltage signals. The VLS3010T-4R7MR80 is a great choice for applications including power supplies, start-up circuits, and extra filtering and noise reduction. It is suitable for use in telecommunication, consumer electronics, gaming consoles, and automotive applications. Thanks to its high current capacity and low DC resistance, the VLS3010T-4R7MR80 can handle high current usages without deteriorating or overheating.

Working Principle

The basic working principle of fixed inductors is quite simple. When current flows through an inductor, a steady magnetic field is built up and stored around the coil. If the current is constant, the magnetic field will remain constant, forming what is known as a fixed inductance. This means the inductance of the inductor cannot be changed and stays relatively constant with small fluctuations due to temperature, frequency and other factors, which is why it is called a fixed inductor. The magnetic field created by the VLS3010T-4R7MR80 is cylindrical in nature with high-flux saturation. This allows for the induction of high rates of current with minimal variations in inductance. Furthermore, the inductor is shielded to ensure better protection against external interference.

Conclusion

The VLS3010T-4R7MR80 is a high-frequency shielded fixed inductor with a rated DC resistance of 0.008 Ohm and a maximum DC current of 4.7A. It is designed for high current applications in telecommunication, consumer electronics, gaming consoles, and automotive fields where extra filtering and noise reduction is required. Its low DC resistance, high current capacity, shielding, and cylindrical inductance make it the ideal choice for the mentioned applications.
