Abstract

In the early days of ferrites, industry employed them at extremely low power levels because the major application at that time was in the telecommunications industry. Since the signal levels were very low, the ferrite core operated in the linear region of the magnetization curve (Rayleigh region) which was characterized by the initial permeability, μo. Chapter 13 describes the action of ferrite cores under these conditions. So ingrained was the electronic industry’s preoccupation with the μo. property of materials that even when higher power level ferrites were developed, the ferrite material was still characterized through the initial permeability. To this day, the principal specification given in ferrite vendors’ catalogs is μo. even through this term has only little relevance to the actual application.
