... equation (17.25). Complex permeability characteristics are shown in figure 17.5. The cut-off frequency, fc is defined as the frequency at which the permeability is half the initial permeability, µ s' , at low frequency. At 25°C, fc for Mn-Zn materials is approximated by fc ≈ 4000/µi (MHz), for µi at ...
