Fixed Inductors are electrical components used to store energy in the magnetic field. They are a passive electronic component, whose basic working principle is that the electric current passing through the coil generates a magnetic field that stores the energy. The flux linkage of this magnetic field is often referred to as inductance, given its vital role in the functioning of electronic circuits. The use of fixed inductors spans a wide range of applications, from switching applications such as DC-DC converters, voltage regulators, audio and radio systems, and power supplies, to various signal processing circuits, including filters, oscillators, and resonators.One great example of a fixed inductor is the SD14-681-R.
