Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 Vrms, Isat, +25 C 5. K-factor: Used to determine B for core loss (see graph). Bp-p = K * L * I. B : (Gauss), K: (K-factor from table), p-p p-p 3. I : DC current for an approximate temperature rise of 40 C without core loss. Derating is necessary for AC currents. L: (Inductance in H), I (Peak to peak ripple current in Amps). rms PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the 6.
