Chinese Professional Air Core Inductive Coils - self-bonding wire inductor air coil for sensors – Golden Eagle

Construction of Air Core Inductors

An inductor is normally created by winding a wire or similar conductor in a coil. A conductor is also placed inside the coil to increase the inductance. An Air core inductor is one that does not include a ferromagnetic core. The term is used to represent inductors which only have air inside or consists of the wire coiled around a non conducting material such as PTFE or glass.

Advantages & Benefits

Air Core conductors have an advantage over conventional ferromagnetic core inductors that the inductance of the air core conductor does not depend upon the value of current it carries and also eliminates the iron losses from magnetic cores. They can also work at higher frequencies than normal due to lower losses and distortion. However the inductance for a coil is low since there is no magnification because of the core so a larger coil needs to be built to achieve a given inductance level.  For this purpose they are widely used in high frequency applications where low inductance is required.
