I22x TYP DCR (mOhms)Core Loss (mW ) = TRF B x (F) x (TRF C x .. I) = DC output current (ADC).. I = Delta I across the Inductor (Amps)F = Switching Frequency (kHz)The Rated Current (Irated) is either the Saturation Current at 25oC or theTemperature Rise Current ; the lowest number of the two Saturation Current (Isat) is the current at which the Inductance dropsby a maximum of 20% below the lower limit of its value specified at 0 ADCBias.

3 Inductance at Isat is measured at the specified Ambient Temperatureby applying DC Bias by a short period of time to minimize the self-heatingeffect of the Temperature Rise Current is the current at which the temperature ofthe part increases by 50oC. This test is performed with the part mounted ona PCB with traces having times the cross sectional area of the copperleads of the part. The temperature of the part is measured after applyingthe DC current for a minimum of 10 is measured at 100 KHz and Rise can be estimated using the following 15%Inductance4@ 0 Adc220300400510120150nH70 Inductance4@ Isat2(25oC) 10%Isat2 (Max Saturation Current)ADC25oC100oC125oC392919147358116 413020157660120473423178770138 Temp.
