(4) K-factor: Used to determine B p-p for core loss (see graph). (2) Irms: DC current for an approximate T of 40C without core loss. Derating is B p-p = K*L*I, B p-p(mT), K: (K factor from table), L: (Inductance in uH), necessary for AC currents. PCB layout, trace thickness and width, air-flow, and I (Peak to peak ripple current in Amps). proximity of other heat generating components will affect the temperature rise.
