Fixed inductors, also known as chokes, are inductors designed with a fixed inductance value. Often found in electronic circuits, they are made to produce a fixed amount of inductance so that their purpose in an electronic circuit can be easily achieved with a set parameter. An example of one of these fixed inductors is the VLF403212MT-4R7M.

The specific application field of the VLF403212MT-4R7M is as a power inductor. It is built to have a high power carrying capacity, and is used in applications such as high frequency DC-DC converters, DC-AC inverters, and noise filtering.

The working principle of the VLF403212MT-4R7M is based on Faraday’s law of induction. According to Faraday’s law of induction, when a changing magnetic field is applied to a conductor, electricity is generated across that conductor. The changing magnetic field in the case of the VLF403212MT-4R7M is created by the oscillation of electric current in the coil. This current in turn creates a field that induces a current in the same or adjacent conductors.

The VLF403212MT-4R7M is composed of several components. The coil, which is at the core of the inductor, is made of either an insulated wire or ribbon. Alternatively, a magnetic core with windings is used in some models. The core material of the inductor is composed of ferrite, powdered iron, or an iron-nickel alloy.

The VLF403212MT-4R7M has several advantages over other power inductors. It is highly efficient due to its low DC resistance and its tight winding geometry. This product is also strong and durable, and can handle significant temperature and power changes. Furthermore, it operates quietly and is also smaller and lighter than other power inductors.

In summary, the VLF403212MT-4R7M power inductor is a highly efficient and reliable fixed inductor, ideal for high frequency DC-DC converters, DC-AC inverters, and noise filtering. Based on Faraday’s law of induction, this product is composed of a coil, core material, and several components that create a fixed inductance value. The VLF403212MT-4R7M has several advantages over other power inductors, which contributes to its efficiency and reliability.
