Air Core Inductor Inductance Calculator

See our other Electronics Calculators.

The following is a design tool which calculates the inductance of an air core inductor. 

L= (d^2 * n^2)/(18d+40l)

where:

L is inductance in micro Henrys,
d is coil diameter in inches,
l  is coil length in inches, and
n is number of turns.

d (coil diameter in inches) (inches)
l (coil length in inches) (inches)
n (number of turns)  

L (Inductance) (uH)

Inductor and Coil Manufacturer Links

The best way to find inductors and coils is to use our free Electronics Component Directory, where a myriad of magnetics manufactures are listed.
