Fixed inductors are small passive electronic components that can store electrical energy in a magnetic field, creating a voltage across a coil once the electric current through it is interrupted. The VLF3012ST-4R7MR91 is an inductor designed to work in high-power applications. It is constructed with a ferrite core and an air gap, which make it an ideal choice for low-ESR applications where stability and temperature performance are critical.

As the name implies, the VLF3012ST-4R7MR91 is a fixed inductor, meaning that its inductance value does not change with changes in current or voltage. The value of the inductance is 4.7 millihenries, which is a relatively low value compared to other types of inductors. This makes it suitable for use in applications where a low amount of noise is required, such as audio and communication circuits.

The working principle of the VLF3012ST-4R7MR91 is based on Faraday’s law of induction. This law states that an electric current produces a surrounding magnetic field and vice-versa. When current is applied to the coil, the ferrite core of the inductor creates a magnetic field that induces a voltage across the coil.

The VLF3012ST-4R7MR91 is commonly used in power supply applications, such as computers, power supplies for electrical and electronic systems, and audio systems. It is also used in RF applications for frequency filtering, impedance matching, and more. Its low inductance value makes it a good choice for use in high-frequency applications where other types of inductors are not suitable.

Moreover, the VLF3012ST-4R7MR91 is incredibly stable and reliable. This is due to the air gap between the core and the inductor’s windings, which prevents the current from becoming too large or too small. This ensures that the inductor works properly and accurately at all times.

In conclusion, the VLF3012ST-4R7MR91 is a fixed inductor that is commonly used in high-power applications, such as computers and audio systems. Its low inductance value makes it an ideal choice for use in frequencies where other types of inductors are not suitable. Furthermore, its reliable and stable performance protects electrical circuits in power supplies and eliminates noise in communication circuits.
