Rxxx: Rxx is inductance value in uH(R:decimal point), x = tolerance,HF=halogen free. ITGYYWW: ITG logo and YYWW is date code. Note: 1> Open Circuit Inductance (OCL) test condition:500KHz,0.25Vrms, 0Adc at 25℃. 2> L @ Isat and L @ Irms Test condition:500KHz,0.25Vrms (Ta=25Ԩ). 3> The nominal DCR is measured from point "a" to point"b", as shown above on the mechanical drawing (Ta=25℃). 4> Isat1, Isat2 & Isat3 : DC current that will cause inductance to drop approximately by 20%. 5> Irms: DC current for an approximate temperature rise of 40℃ without core loss. Derating is necessary for AC currents. PCB pad layout,trace thickness and width,air-flow and proximity of other heat generating components will affect the temperature rise. It is recommended the part temperature not exceed 130°C under worst case operating conditions as verified in the end application. ● New York 1 914 347 2474 ● Taipei 886 2 2698 8669 ● Kaohsiung 886 7 350 2275 ● Tokyo 81 3 5829 8676 ● Shenzhen 86 755 8418 6263 ● Shanghai 86 21 5424 5141 ● Hong Kong 852 9688 9767 ● sales@inter-technical.com ● www.inter-technical.com Revision D: March 15, 2015 AH43328B Series Inductance vs. Current 4.
