L @ Isat and L @ Irms Test condition: 500KHz , 0.25Vrm (Ta=25℃). 3. The nominal DCR is measured from point “a” to point “b” as shown above in 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. 6. Derating is necessary for AC currents. Verify and check PCB pad layout, trace thickness, width, air-flow and proximity of other heat generating components as it will have an effect on the temperature rise. 7. It is recommended that the part temperature should not exceed 130°C under worst operating conditions. ● ● 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 E.2: January 19, 2021 *Due to continuous product improvement, all specifications are subject to change without prior notice.
