Fixed Inductors are a type of electrical component that are used to control currents in electrical circuits. The VLS3012ET-220M-CA is an example of a fixed-inductor. It is a flat copper-clad aluminum wire-wound coil constructed with a small 0805 size for easy insertion and soldering in modern printed circuit board (PCB) assemblies. The inductor produces a stable current, which can help reduce unwanted electromagnetic interference (EMI) in sensitive circuits.

The VLS3012ET-220M-CA Fixed Inductor has an inductance range between 0.2 to 2.2 µH, a saturation current of 22 A, a resistance range of 0.4 to 4.4 mΩ and a maximum operating temperature of +125°C. The VOCL aspect ratio of this coil is 15:1. Other features include a low DCR, high frequency operation, low core losses, high-temperature stability, low profile, and small size.

The operating principle of the VLS3012ET-220M-CA fixed inductor is simple. A fixed inductor functions as an electrical transformer to reduce the voltage of an alternating current. It does this by producing an alternating back electromotive force (EMF) and current that is higher than the input current, thereby reducing the voltage. To achieve this, the inductor uses a core, which is an electrically conducting material such as iron that magnifies the effect of these AC currents.

The main application of the VLS3012ET-220M-CA fixed inductor is in the field of power supply. It is used in power supplies to reduce the voltage of alternating current so that low current levels can be achieved. This component is also used in other applications such as in telecommunications, computer systems, and automotive electronics. It is also used in various other consumer electronics products such as smartphones, tablets, and televisions.

In summary, the VLS3012ET-220M-CA fixed inductor is a small flat copper-clad aluminum wire-wound coil that has a wide range of inductance, saturation current, and resistance. It is mainly used in power supplies to reduce alternating current voltage levels but can also be used in other applications such as telecommunications, computer systems, and automotive electronics. The operating principle of the fixed inductor is to produce an alternating back EMF and current higher than the input current thereby reducing the voltage.
