These inductors are available in two different constructions including a square cross section construction and a ultra violet glue molded construction for easier handling. Mechanically an inductors core provides support for its windings.

The combination of winding turns and volume of magnetic material sets an upper limit on the maximum allowable magnetic flux a core can sustain.

Use of air core inductor. Air core inductor coil inductance calculator the following is a design tool which calculates the inductance of an air core inductor. In addition these inductors are an ideal solution when space is not prohibitive. Magnetically an inductors core provides the medium to concentrate and contain magnetic flux.

An air core inductor is a wire coil with no solid core inside the coil. The formula for inductance of a single layer air core inductor can be expressed as d 2 n 2 18d40z. What is an air core coil.

Well use the term air core coil to describe an inductor that does not depend upon a ferromagnetic material to achieve its specified inductance. Air has a low electrical conductivity and so produces the weakest of all magnetic fields in opposition to current flow. This covers the cases where there really is just air inside as well as windings upon a different insulator such as bakelite glass or ptfe etc.

Air core inductors the avx series of air core inductors feature very high q 100 in miniature to larger sizes for rfmicrowave applications. D coil diameter in inches. Air core inductors provide effective solutions for switch mode magnetic requirements especially when focusing on high linearity high frequency and reduced core loss.
