Single layer air core inductor design calculator

single layer inductor

Winding the wire in a single layer produces an inductor with minimal parasitic capacitance, and hence gives the highest possible self-resonant frequency (SRF). Striving to obtain a high SRF and low losses is the key to producing coils which have radio-frequency properties bearing some useful resemblance to pure inductance. The calculation is based on Harold A. Wheeler’s 1928 formula for …
