RF Inductor Calculator was developed to help users predict the RF characteristics of a single-layer solenoid-style air-core inductor. <br><br>
<u>Inputs via the slider widgets:</u>
<ul>
<li>&#8960a : Conductor diameter in millimeters (mm). Estimated equivalent AWG wire size is also displayed where appropriate.</li>
<li>&#8960a : Outer conductor diameter in millimeters (mm). Equivalent coax cable size is also displayed.</li>
<li>&#8960b : Loop diameter in millimeters (mm).</li>
<li>c/a : 'c' is the inter-winding spacing, and 'a' is the conductor diameter, so 'c/a' is the spacing ratio. (Must be >= 1.1)
A low-value will increase the resistance due to the proximity effect.</li>
