VLP8040T-221M Inductors, Coils, Chokes

Fixed inductors such as the VLP8040T-221M are used in a variety of applications including power filters, common mode chokes, switching converters, and more. In power filters, the fixed inductor is typically used in low frequency filtering applications, such as in cell phone chargers. The inductor helps to reduce the amount of interference generated by the electronics during shock or surge events. In common mode chokes, the inductor is used to suppress high frequency noise generated by electronic equipment. Common mode chokes are typically used in automobile systems and medical imaging equipment. In switching converters, the fixed inductor is used to store magnetic energy during periods of low current in order to supply higher current during periods of high current demand. It is this stored energy that helps to improve the efficiency of the switching converter.

The VLP8040T-221M is a type of fixed inductor that uses a wire coil to generate the magnetic field. The wire coil has a number of turns that contain wire of a certain diameter and length. When an electric current is applied to the wire coil, a magnetic field is generated. This magnetic field is then stored in the inductor and can be used at a later time to supply a current. The size of the inductor itself determines the amount of magnetic field that can be stored. When the stored energy is no longer needed, the inductor will slowly dissipate the energy back into the circuit.
