Derating is necessary for AC currents. PCB pad layout, trace thickness and width, air-flow and proximity of other heat generating components will affect the temperature rise. It is recommended the part temperature not exceed 125C under worst case operating conditions verified in the end application. 3 Isat: Peak current for approximately 20% rolloff at +25C. 4 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * I. Bp-p (mT): (Gauss), K: (K-factor from table), L: (inductance in H), I (peak-to-peak ripple current in amps). 5 Part Number Definition: FP1308-xxx-R * FP1308 = Product code and size * xxx= Inductance value in H, R = decimal point.
