    Air\ Core\ Flat\ Spiral\ Inductance = \frac{(4.921 \times N^2(d_1+d_2)^2)}{(15d_1-7d_2)} \times dimension

    where,

    • N = the number of turns
    • d1=outer diameter
    • d2=inner diameter
    • if the dimension unit is mm then dimension=1. if the dimension unit is mils then the dimension is 0.0254
