Fixed Inductors

Fixed inductors are electrical components used in a wide range of applications, such as filtering, buffering, and communications systems. They are also referred to as chokes or discrete inductors. The most common type of fixed inductors is the wire-wound inductor, which consists of a coil of metal wire wound on a cylindrical form, with the core material being ferrite, powdered iron, or air.

Additionally, the component is often employed in RF circuitry, including filters, antenna tuners, and VCOs.

Working Principle

An inductor works by storing and releasing energy in the form of a magnetic field. It operates on the principle of inductance, which states that when a current is applied to a coil of wire, a magnetic field is created around the coil. This magnetic field then induces a voltage on the coil, which can be used to regulate and control the amount of current passing through the coil. The VLF504012MT-220M has an anti-saturation construction, which helps ensure that the inductance remains stable even when the current drawn from the inductor is increased. This allows the inductor to be used in a variety of applications, including those with high power loads.

Conclusion

The VLF504012MT-220M is a fixed inductor ideal for applications requiring high power filtering, voltage regulation, and energy storage. It is made of a ferrite core and enameled wire and features an anti-saturation construction for greater inductance stability. The component operates on the principle of inductance, whereby an applied current creates a magnetic field that induces a voltage on the coil.
