注释

When ordering, please specify packaging code: WA8351-ALC
Inductance is tested between pins 4 and 6 at 100 kHz, 1.0 Vrms, 0 Adc.
DCR is with the primary windings connected in series and the secondary windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is measured between pins 4 and 6 with all other pins shorted.
500 Vrms, one minute isolation (hipot) between primary and secondary.
