Working Principle of 4379-221HS Fixed Inductors

The 4379-221HS fixed inductors are made of ferrite cores and coils. To begin with, the ferrite cores are made from a ferrous metal alloy pressed into pieces. The core is then magnetized. As a result, when a voltage is applied to the coils, a magnetic field is generated in the core and induces a voltage in the wire. The induced voltage is dependent on the strength of the external magnetic field and the number of windings on the coil.In other words, the current in the coil creates a magnetic field in the core, which in turn creates a voltage across the coil. This voltage is proportional to the amount of current that is flowing. In detail, the inductance of a 4379-221HS inductor is related to the size of the core, which means the bigger the core size, the higher the inductance. In addition, the inductance can be further increased by winding more turns of wire around the core.
