OCL@-40 °C can be lower than OCL@+20 °C by 15% max. 2) Irms: DC current for an approximate DT of 40 °C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed +125 °C under worst case operating conditions verified in the end application. 3) Isat1: Amperes Peak for approximately 30% rolloff (@+25 °C) 4) Isat2: Amperes Peak for approximately 30% rolloff (@+125 °C) DCR mΩ@20°C (Typical) 0.83 0.83 1.58 1.58 2.58 2.58 4.08 4.08 6.0 6.0 DCR mΩ@20°C (Maximum) 1.00 1.00 1.90 1.90 3.10 3.10 4.90 4.90 7.2 7.2 K-factor (5) 21 21 14 14 10 10 8.3 8.3 6.9 6.9 5) K-factor: Used to determine B p-p for core loss (see graph).
