Air Coil Inductor,A type of inductor or a wire coil without a magnetic core in the coil is known as an air core inductor or air coil inductor. In this inductor, an air core ensures a lower peak inductance, however, it also decreases the energy losses associated by means of ferrite inductors. The lack of core losses permits air core inductors to function at maximum frequencies.
These types of inductors are utilized whenever the amount of inductance is less required and they do not have a core loss because there is no core. However, the number of turns in this inductor should be more as compared to other inductors which have the core. Generally, ceramic inductors are frequently called air-core inductors. These inductors provide efficient solutions especially for switch mode magnetic requirements when focusing on high frequency, high linearity & reduced core loss. The air core inductor's basic construction is, it consists of coils with a number of wire turns that are wounded on ordinary cardboard. So, ceramics or plastic former may be utilized as an insulating material.
Working Principle These inductors work on the basis that air has a fairly minimum electrical conductivity. So the air-core inductance is also low, producing a weak magnetic field. Because of the small magnetic field generation of air cores', it achieves a faster current rise while avoiding signal loss. This loss mainly happens whenever an inductor generates high magnetic field strengths within an electric circuit.
