A 0.061 [1.55] Add an "R" to the part number after "P" for the RoHS compliant version (i.e. 59PR9871N is the RoHS compliant version of 59P9871N). Trise (oC) = Core Loss + DCR Loss TRF A 0.833 DCR Loss (mW) = Idc2 + … I 2 2 x TYP DCR (mOhms) Core Loss (mW) = TRF B x (F)1.84 x (TRF C x … I)2.28 IDC = DC output current (ADC) … I = Delta I across the inductor (Amps) F = Switching frequency (kHz) The Saturation Current (Isat) is the current at which the Inductance drops by a maximum of 20% below the lower limit of its value specified at 0 ADC Bias. Inductance at Isat is measured at the specified Ambient Temperature by applying DC Bias by a short period of time to minimize the self-heating effect of the component. The Temperature Rise Current is the current at which the temperature of the part increases by 50oC. This test is performed with the part mounted on a PCB with traces having 1.7 times the cross sectional area of the copper leads of the part. The temperature of the part is measured after applying the DC current for a minimum of 10 minutes. Inductance is measured at 100 KHz and 1.0 Vrms. Temperature Rise can be estimated using the following formulas: 1. 2. 3. 4. 59P9870N 59P9871N 59P9872N 59P9873N 59P9874N 59P9875N 59P9876N 0.307 [7.80] 0.299 [7.60] P/N MAX Dimension A 0.299 [7.60] 0.295 [7.50] 0.295 [7.50] 0.295 [7.50] 0.295 [7.50] ± 15% Inductance3 @ 0 Adc 220 300 400 510 120 150 nH 70 Inductance3 @ Isat1 (25o C) MIN nH 150 204 272 347 82 102 48 Isat1 (Max Saturation Current) ADC 25oC 100o C 125oC 39 29 19 14 73 58 116 41 30 20 15 76 60 120 47 34 23 17 87 70 138 Temp.
