Inductance and leakage inductance are measured at 10kHz, 0.1Vrms. 2. Rated current is the approximate DC current at which DT is 40C. Part temperature should be verified in the end application. The part temperature (ambient plus temperature rise) should not exceed 125C under worst case operating conditions. 3. Schematic 1: - Inductance and DCR are measured at N1 or N2 - Leakage inductance is measured at N1 (pin 1-2) with N2 (pin 4-3) winding shorted 4. Schematic 2: - Inductance and DCR are measured at N1, N2, N3 or N4. - Leakage inductance is measured at pin (1-3) or (2-4) with other pins shorted Ordering Information Packaging HA19 10000 LF One shipping Part Number carton Lead Free Model Series HA19-10000LF 400pcs HA19-20000LF 400pcs Sequence number HA19-30000LF 280pcs HA19-40000LF 400pcs HA19-50000LF 396pcs HA19-60000LF 210pcs General Note TT Electronics reserves the right to make changes in product specification without TT Electronics BI Technologies TT Electronics BI Technologies www.ttelectronics.com magsales ttelectronics.com notice or liability.
