(2) irms: dc current for an approximate ? t of 40 without core loss. derating is necessary for ac currents. pcb layout, trace thickness and width, air-flow, and pro ximity of other heat gener ating components will affect the temperature rise. it is recommended that the temperature of the part not exceed 125 under worst case operating conditions verified in the end application. (3) isat amperes peak f or approximately 35% rolloff max. (@25) (4) k-factor: used to determine b p-p for core loss (see graph). b p-p = k*l* ? i, b p-p(mt), k: (k factor from table), l: (inductance in uh), ? i (peak to peak ripple current in amps).
