The VLF403212MT-220M-CA is a type of fixed inductor, a type of electromechanical device designed to store and release electric energy when needed. Fixed inductors have a variety of applications, but are most commonly used in electronic circuit design, especially in high frequency circuits. They are also used in power supplies, radio, telecommunications, and military applications.

A fixed inductor may be defined as a two-terminal component which stores electrical energy in the form of a magnetic field when current passes through the coil. When the current stops, the magnetic field collapses, and the energy is released. This process is known as inductance, and is measured in units of henry.

The VLF403212MT-220M-CA is a fixed inductor manufactured by Vishay Intertechnology. It has a rated per-unit inductance of 2200nH and a rated current of 0.075A-2.4A. The package dimensions are 0.34" (8.6mm) × 0.18" (4.5mm). This fixed inductor operates over an extended temperature range of -55°C to +125°C.

The major applications of the VLF403212MT-220M-CA include power supplies, switches, routers, automobiles, monitors, and other high-frequency digital equipment. The inductor is particularly well-suited to power supply applications, because it is capable of absorbing switching noise in power supplies and keeping a steady state inductance even when subjected to changes in surrounding temperature.

The working principle of the VLF403212MT-220M-CA is based on Faraday’s law of induction, which states that a changing magnetic field will induce a current in a coil. When current passes through the coil, a magnetic field is created. This magnetic field stores energy, and when the current stops, the stored energy is released. This energy is then used to drive a load.

The VLF403212MT-220M-CA is a reliable, cost-effective, and widely-used fixed inductor designed for a range of applications. Its extended temperature range ensures it is suitable for operation in warm or cold environments, while its high-inductance allows it to absorb switching noise in power supply designs.
