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 125°C under worst case operating conditions verified in the end application. 3 Isat: Peak current for approximately 30% rolloff at +20°C. 1109 BU-SB091064 Isat3 (Amps) 3.07 2.42 2.00 1.59 1.31 1.12 1.02 0.90 0.75 0.61 0.51 0.42 0.177 0.145 0.122 0.101 0.083 DCR (Ω) @ 20°C (Typical) 0.041 0.051 0.074 0.113 0.162 0.232 0.257 0.295 0.440 0.676 0.986 1.21 4.77 7.40 9.20 13.70 20.90 K-factor4 84 68 57 56 39 32 29 26 21 18 14 12 6 5 4 3 3 4 K-factor: Used to determine Bp-p for core loss (see graph).
