(3) Isat Amperes peak for approximately 20% rolloff (@20°C) (2) Irms: DC current for an approximate ΔT of 40°C without core loss. Derating is (4) Isat Amperes peak for approximately 30% rolloff (@20°C) necessary for AC currents. PCB layout, trace thickness and width, air-flow, and (5) K-factor: Used to determine B p-p for core loss (see graph). proximity of other heat generating components will affect the temperature rise. It B p-p = K*L*ΔI, B p-p: (Gauss), K: (K factor from table), L: (Inductance in uH), is recommended that the temperature of the part not exceed 105°C under worst ΔI (Peak to peak ripple current in Amps). case operating conditions verified in the end application.
