VLF403210MT-6R8M Inductors, Coils, Chokes

Fixed Inductors

Inductors are components that are designed primarily to store energy. They are also known as coils, chokes and reactors, and are used in a variety of electronic applications. One type of inductor is the VLF403210MT-6R8M, and this article will explain its application, operation, and role that it plays in electronic circuits.

VLF403210MT-6R8M: Application

The VLF403210MT-6R8M is a fixed inductor with a rated inductance of 4.7uH, a DC resistance of 0.6Ω, and is designed for use up to an operating frequency of 1MHz. It is most commonly used as an input choke in switched mode power supplies (SMPS) such as chargers, laptop adapters, and desktop PCs. It is also used in DC to DC converters, voltage regulators, and power inverters.

VLF403210MT-6R8M: Working Principle

At its most basic level, an inductor is comprised of a coil of wire. When connected in an electric circuit, current will flow through it. This causes a magnetic field to be generated, which in turn stores energy. When current stops flowing, the magnetic field collapses and the stored energy is released into the circuit. This is known as the inductive effect.

In the case of the VLF403210MT-6R8M, this is used as an input choke, which acts as a low-pass filter for signals. This helps to reduce electromagnetic interference (EMI). It also helps to reduce ripple and noise levels at the output of the power supply, providing a clean DC voltage that varies within acceptable limits.

The inductor is also designed to operate up to a frequency of 1MHz. This is beneficial for applications such as switching power supplies and DC to DC converters that require higher frequency operation. The higher frequencies allow for greater efficiency from the power supply due to reduced switching losses, which in turn could lead to savings on energy bills.

Conclusion

The VLF403210MT-6R8M is a fixed inductor with an inductance rating of 4.7uH and a resistance of 0.6Ω, which is designed for use up to an operating frequency of 1MHz. It is primarily used as an input choke in switched mode power supplies, as well as DC to DC converters, voltage regulators, and power inverters. Its inductive effect helps to reduce ripple and noise levels, as well as reduce interference levels in the output of the power supply, providing a clean DC voltage.
