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. 4 Isat: Peak current for approximately 20% rolloff at +25°C. 0209 BU-SB08890 DCR (mΩ) @ 20°C K-factor6 0.32 ± 9.4% 233 233 233 233 233 0.53 ± 10% 233 233 233 233 233 0.18 ± 20% 233 233 233 233 233 5 Isat2: Peak current for approximately 20% rolloff at +125°C. 6 K-factor: Used to determine Bp-p for core loss (see graph).
