Open Circuit Inductance (OCL) and L@Irms and L@Isat are measured at 10KHz,0.25V@ 25ºC. 2. Isat: DC current that causes inductance to drop by approximately 35% from OCL (Ta=25℃). 3. Irms: DC current that causes an approximate temperature rise (△T) of 40℃ (Ta=25ºC). ● ● 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 A.0: June 13, 2019 *Due to continuous product improvement, all specifications are subject to change without prior notice.
