Iron-Core Inductance Design Chart
November 1946 Radio-Craft

 

November 1946 Radio-Craft

November 1946 Radio Craft Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Craft, published 1929 - 1953. All copyrights are hereby acknowledged.

This iron core inductance design chart was included along with an article in the November 1946 issue of Radio-Craft magazine titled, "Coils, Cores and Magnets." Both the chart and the article were written by Mr. H. W. Schendel. Iron-core inductors, with their high permeability and loss factor (due to eddy currents), can only be used in power supply filtering, audio, and other relatively low frequency (<~500 kHz) applications. Ferrite cores are compressed from slurries of iron, nickel, cobalt, and other metallic elements, all of which experience lower eddy current losses because they are generally not electrically conductive. With lower permeabilities, ferrites can operate into the few hundreds of MHz realm. Physical configuration of the core and conductors wrapped around the core can have a large influence on the electrical parameters of power loss, impedance, frequency of operation, linearity (due to saturation), heat dissipation, etc.
