Bp-p = K * L * ΔI * 10-3. Bp-p (Gauss), K: (K-factor from table), L: (inductance in nH), ΔI (peak-to-peak ripple current in amps). 7 Part Number Definition: FP1308Rx-Rxx-R 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 125°C under worst case operating conditions verified in the end application. • FP1308 = Product code and size • Rx = DCR indicator • Rxx = Inductance value in μH, R = decimal point. • “-R” suffix = RoHS compliant 4 Isat: Peak current for approximately 20% rolloff at +25°C.
