Introduction:

Fixed inductors are a type of electrical component mainly used to store energy in the form of electromagnetic fields. In particular, this type of component has a coil wound of wire, usually made of iron, copper or any other wires suitable for winding. An electrical current passes through the coil, which generates a magnetic field. This field will be able to contain the energy present within the wire, even when the current stops. The VLF403215MT-4R7M-CA is a fixed inductor featuring a 4.7µH inductance suitable for a range of applications and settings.

VLF403215MT-4R7M-CA Features and Applications:

This type of inductor is manufactured by Vishay, a well-known electronics component company. The VLF403215MT-4R7M-CA is classified as a fixed inductor for its two windings. The winding materials are metalized polyester, with the self-resonant frequency as low as 15 MHz. In addition, its saturation current is 2.5A, and its DC resistance is 0.158 Ohms, while the maximum operating temperature is +125°C. The wide range of performance parameters make the VLF403215MT-4R7M-CA suitable for a variety of applications. Its size is ideal for high-density circuit designs, and its high inductance gives it good stabilization properties. This makes it suitable for applications where stability or isolation from other signals is required. Some of the more common applications for the VLF403215MT-4R7M-CA are in the areas of computer and communication components, automotive, industrial controls, audio systems, military and aerospace applications, and medical devices.

Working Principle:

The basic working principle of any fixed inductor is the same. An electrical current is transmitted through the inductor, either in DC or AC, which in turn generates a magnetic field. This magnetic field stores the energy carrying the current. When the current is stopped, the magnetic field dissipates. This is how an inductor works. The VLF403215MT-4R7M-CA is made up of two windings of metalized polyester. This material has low losses, meaning that the magnetic field generated by the current is not dissipated as quickly as it would with other materials. The metals used also provide additional shielding against interference, making it ideal for use as a filter or for applications where variable currents are present.

Conclusion:

The VLF403215MT-4R7M-CA is a fixed inductor with two windings of metalized polyester. It is suitable for a range of applications, including high-density circuit designs, noise filtration and stability, audio systems, military, and medical devices, among others. It is made up of two windings, which generate a magnetic field that stores the energy of the electrical current. The low losses of the material and its shielding properties make it an ideal component for a wide range of applications.
