Fixed inductors, like the LAL02VA820K, are electrical components specially designed to offer an inductance value that has been predetermined. The inductor is made from a coil of wire containing a magnetic core, typically made from iron. The inductance of an inductor is a measure of its ability to store energy in a magnetic field, when the electric current delivers to it. An inductor is typically used for impedance matching and signal filtering applications.

The LAL02VA820K is a fixed inductor which has an inductance of 820nH and features an exclusion radius of 5.7mm. The component uses a wire wound construction to create the inductive loop and supplies a high current rating of 4.3A. The LAL02VA820K is rated to an operating temperature range of -40°C to +125°C, with a storage temperature range of -40°C to +85°C.

In terms of application fields, the LAL02VA820K is mainly used in power systems, to store energy in DC-DC converters, voltage regulators, inrush limiters, and HID lighting systems. Due to its high current rating, this inductor is also suitable to be used as a snubber coil for high voltage applications, and for applications like energy storage in customers’ rectification systems.

The working principle of the LAL02VA820K is mainly based on electromagnetic principles. When an electrical current passes through it, an electric field and a radial magnetic field are created. This is due to the nature of the wire wound construction of the inductor, in which the current generates a magnetic flux. To ensure this flux remains uninterrupted, a special magnetic core is used. This magnetic core creates a magnetic circuit which is designed to protect the inductor from external magnetic fields and also keeps the current flow within the inductor.

In conclusion, the LAL02VA820K is a fixed inductor that is designed for a range of power systems applications. Its isolation radius of 5.7mm allows this component to be used in high voltage applications, while its high current rating of 4.3A ensures it is suitable for energy storage and power management. The inductor is based on simple electromagnetic principles, in which the inductance is determined by the number of inductive loops and the strength of the core material used. As such, the LAL02VA820K is an ideal solution for customers whose applications require an inductor with high current and power ratings.
