Fixed inductors are components with an electrical winding which can store a set amount of energy. They are often found in applications that need to "hold" electrical current in a certain manner. One subsubfamiliy of these components are the electronic inductors, and within this family there are several variations. One such variation is the VLCF4028T-6R8N1R3-2.

Application Field

VLCF4028T-6R8N1R3-2 is a type of fixed inductor typically used in power electronic applications such as power supply circuits, Voltage Regulator Modules (VRM) and power factor correction modules (PFC). It features a current carrying capacity of 6A and a resistance of 0.8 Ohms. It is also designed with an operating temperature range from -55~105°C so it can be used in a wide range of temperatures. Additionally, the VLCF4028T-6R8N1R3-2 is marked with a height of 12.0mm, a diameter of 18mm, and a tolerance of 10%, making it easier to find a place to install it in the circuit.

Working Principle

The VLCF4028T-6R8N1R3-2 is a type of fixed inductor which operates according to the principles of Faraday\'s Law of Induction. This law states that when a current is flowing in a wire, a magnetic field is created surrounding the wire. This magnetic field induces an electromagnetic field which induces a current in other nearby wires. This phenomenon is called Self Inductance. In its simplest form, a fixed inductor is made up of two coils of wire wound around a magnetic material. This material concentrates the magnetic field created by the electric current, increasing the self-induced, or counteracting, current in the other wire.

The VLCF4028T-6R8N1R3-2 works similarly, but with the addition of electronic components to modify the operation of the inductor. By adding these electronic components, it is possible to adjust the properties of the inductor to better suit the application. For example, it is possible to adjust the resistance of the inductor and the amount of current that it can carry. This makes it possible to tailor the inductor to the specific requirements of the application, allowing it to be more efficient and reliable.

In power circuitry applications, the VLCF4028T-6R8N1R3-2 is often used to maintain a constant current, or to transform or filter voltage or current. In Voltage Regulator Modules (VRMs) and other applications, the inductor is used to filter out harmonic frequencies and other noise, while still allowing the flow of power. In power factor correction modules (PFCs) it is used to reduce the stresses of switching power stages by providing a constant current to the system.

Overall, the VLCF4028T-6R8N1R3-2 is a type of fixed inductor with very versatile applications in many different power electronic circuits. By using the principles of Faraday\'s Law of Induction, the addition of electronic components, and its ability to adjust its properties, the VLCF4028T-6R8N1R3-2 is capable of providing reliable and efficient power control in a variety of applications.
