Fixed Inductors
Fixed Inductors are components designed to store energy by gathering magnetic fields. This type of electronic part consists of one or more windings of insulated wire. These windings are wrapped around a core material like ferrite which increases the inductance. In the simplest form, an inductor behaves like an electric current when no voltage is applied, but acts like an electromagnet when voltage is applied.
B82111E0000C021 Application Field and Working Principle
The B82111E0000C021 is a type of fixed inductor. This particular model exhibits large inductance with low DC resistance. It is primarily used in power supply systems, for applications such as power supplies for computers and other consumer electronics. In addition, fixed inductors like the B82111E0000C021 can also be used in automotive and industrial applications such as motor control, voltage regulators, and power converters.
The working principle of the B82111E0000C021 is simple- when voltage is applied, current will flow through the inductor. The current flowing through the inductor will cause an electromagnetic field that is generated around the inductor, which will cause a voltage to be induced back into the inductor. This causes a counter-electromagnetic flux to be generated in the opposite direction of the applied electric field. The amount of voltage induced back into the inductor is proportional to the inductance of the component. This process is also known as inductive reactance, and is what creates the inductor’s characteristic of storing energy.
The B82111E0000C021 also has the ability to filter out unwanted noise. The inductor’s ability to filter out noise is due to the fact that high frequency noise signals require more current to flow through the inductor than the design of the inductor can handle. This causes the high frequency noise signals to become attenuated as they enter the inductor and subsequently flow through the circuit.
Overall, the B82111E0000C021 is a fixed inductor that is capable of storing energy, filtering noise, and handling relatively high currents.
