ITGYYWW: ITG is Company name , YYWW is date code. 1. Open Circuit Inductance (OCL) test condition: 100KHz,1.0Vrms,0Adc at 25Ԩ. 2. L @ Isat and L @ Irms Test condition: 100KHz,1.0Vrms (Ta=25Ԩ). 3. The nominal DCR is measured from point "a" to point"b",as shown above on the mechanical drawing (Ta=25Ԩ). 4. Isat1 & Isat2 : DC current that will cause inductance to drop approximately by 20%. 5. Irms: DC current for an approximate temperature rise of 40Ԩ 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. 6. 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 Japan 81 568 85 2830 ● Shenzhen 86 755 8418 6263 ● Shanghai 86 21 5424 5141 ● Hong Kong 852 9688 9767 ● sales@ITG-Electronics.com ● www.ITG-Electronics.com Revision C: July 06 , 2016 *Due to continuous product improvement, all specifications are subject to change without prior notice.
