I hope, that this small application will help for radio-hobbyists to calculate various inductors.

This software allows to calculate the following species of inductors:

In all variants, that are below, it's possible to calculate number of turns if inductance is known or inductance if number of turns is known
  • RF air core inductor as single turn loop
  • Single layer close-winding air core solenoid
  • Single layer RF solenoid with winding pitch
  • Single layer RF solenoid with pitch, but noncircular windings
  • Multilayer air core inductor
  • Toroidal air core one-layer coil inductance
  • Coil or choke on a ferrite ring (only for low-current RF circuits)
  • Coil or choke in the pot core (ferrite or powder iron, only for low-current RF circuits)
  • The planar PCB coil
  • The software has additional modules that allow calculating:
    • flat PCB coil with the meander form of turns;
    • multilayer PCB inductors;
    • an inductor as a rectangular one turn loop;
    • estimate influence of the shield on the value of coil inductance;
    • multi-winding round loop with round cross-section;
    • a multi-layer inductor with rectangular former
    • ferrite rod core inductor;
    • finding unknown permeability of a ferrite ring;

In what of an advantage of this software before analogs?

  • The program calculates the inductance of different species of inductor design. It is possible to select an optimal variant, to use available coil-former or recalculate inductor to other dimensions.
  • Coil32 allows estimating Q-factor of RF single layer air core inductor.
  • It's possible to estimate the length of wire what needed to wind one layer, multilayer coil and the coil on a ferrite ring.
  • Results of all calculations are deduced in a common text box, from where they can be saved in a file or print out.
  • For flat coil inductors on the PCB, the program prompts the optimal sizes for highest Q-factor.
  • It's possible to use metric or inches as units of measurements.
  • AWG or metric wire gauge support.
  • It is possible to develop additional plugins for the program to calculate a different kind of coils and chokes.
  • The program is freeware.
  • Multilingual interface support.
  • The soft is multiplatform. There are versions for Windows, Linux, MacOS & Android.
