Notes

When ordering, please specify turns ratio and packaging codes: e.g. HTX7045C-144CRC
Turns ratio: A = 1 : 1, B = 2.5 : 1, C = 2 : 1, D = 1.5 : 1, E = 1.33 : 1, F = 1.2 : 1
Inductance measured at 100 kHz, 0.1 Vrms, 0 ADC on an Agilent 4263B (or equivalent).
DCR is measured on a Keithley 580 Micro-ohmmeter (or equivalent).
Leakage Inductance LL is measured at 100 KHz, 0.1 Vrms on an Agilent 4263B (or equivalent). Sec is shorted for PRI LL / PRI is shorted for SEC LL.
