Fixed inductors play an important role in electronic circuits, as they are the primary component responsible for providing stability and preventing unwanted feedback. The VLS4012ET-220M is one such fixed inductor, a chip-scale device that is designed for high current inductive applications. It is suitable for a wide range of applications, from automotive electronics to consumer electronics and telecom systems. This article will discuss the VLS4012ET-220M\'s applications and working principles.

Application Field

The VLS4012ET-220M is a surface-mount, chip-scale inductor, with a maximum working voltage of 220V. It offers a wide range of current handling capabilities, from 0.2A to 5A. Thanks to its high current handling abilities, it is suitable for a variety of automotive, consumer electronics, and telecommunications applications. For example, it can be used to construct a low-voltage DC/DC converter, a low-pass filter, or an active rectifier. Additionally, it is also used in power supply designs, EMC protection circuits, and onboard power systems.

The VLS4012ET-220M has several advantages over other chip-scale inductors. First, it offers excellent temperature stability compared to other fixed inductors. This makes it suitable for high temperature applications, such as automotive electronics. Second, it has low power loss, which allows it to be used in energy-efficient designs. Finally, it has a low profile design that reduces board space and makes it ideal for tight-space designs.

Working Principle

The VLS4012ET-220M is an inductor that works on the principle of self-induction. In this process, a coil of wire carries an electric current, creating a magnetic field surrounding the coil. When the current passes through the coil, it induces an electromotive force in the coil, creating a potential difference between the two ends of the coil. This potential difference is referred to as the induced voltage or back electromotive force.

The VLS4012ET-220M uses this self-induction process to control the flow of current. It contains a core, usually made of ferrite or iron, which is wrapped in a wire coil. This coil carries an electric current, which creates a magnetic field around the core. When a direct current (DC) is applied to the coil, it creates a magnetic field in the core that opposes the flow of current. This process is known as inductive reactance, and it allows the inductor to control the flow of current in the circuit.

The VLS4012ET-220M also has the ability to store energy in the form of a magnetic field. When a direct voltage is applied to the coil, it creates a magnetic field in the core that stores electric energy. When the voltage is removed, this energy is then released back into the circuit, allowing the inductor to continue to control the current flow.

Conclusion

The VLS4012ET-220M is a chip-scale, surface-mount fixed inductor that is suitable for a wide range of applications. It is capable of handling high currents and offers excellent temperature stability, low power loss, and a low profile design. Its working principle is based on the self-induction process, wherein a current passing through a wire coil creates a magnetic field that causes a back electromotive force, controlling the flow of current in the circuit. Finally, it is also capable of storing energy in the form of a magnetic field, allowing it to continue to control the current flow in the circuit.
