I : DC current for an approximate temperature rise of 40C without core loss. De-rating is necessary for AC currents. B = K * L * DI.B : (Gauss), K: (K-factor from table), L: (inductance in H), rms p-p p-p Temperature rise is dependent upon several factors, including the PCB pad layout, trace thickness and width, air-flow DI =(peak-to-peak ripple current in amps). and proximity to other heat generating components. It is recommended the part temperature not exceed 125C under 5. Part Number Definition: MPI4040RX-XXX-R worst case operating conditions and therefore, the temperature rise should be verified in the end use application.

I : Peak current for approximately 30% rolloff at +25C. XXX = inductance value in H, R= decimal point - If no R is present, then last character equals the sat number of zeros -R suffix = RoHS compliant Transient pulse not to exceed 1 millisecond.
