inductor
An inductor is a passive electronic component that stores energy in a magnetic field. It works by converting electrical energy into a magnetic force which then can be used elsewhere. A general application area for inductors would be as filters (oscillators), modems and so forth. Its major role is to produce a voltage induced in the conductor by changing magnetic field. Technological characteristics of an inductor include its inductance value (measured in henries [H]), which is a measure of energy storage ability and its ability to handle high frequencies without significant loss of signal information. The choice of core material (such as iron or nickel) determines both saturation level and inductor efficiency. The core material, such as iron, nickel, or cobalt, actually decides the efficiency and saturation level of the inductor. Inductors are used in a wide variety of electronic devices and systems, including power supplies, filters, sensors and energy storage systems to name just a few examples. They play an essential role in signal integrity and maintaining stable operation of electronic circuits.
