注释

Inductance measured on an Agilent/HP 4284 at 200 kHz, 0.5 Vrms, 0 Adc with windings connected in parallel.
DCR for primary is measured with the windings connected in parallel. DCR for secondary is measured between pins 7 and 11.
Leakage inductance is for the primary with windings connected in parallel, measured at 200 kHz, 0.5 Vrms, 0 Adc with all secondary pins shorted.
Volt-time product is based on primary windings connected in parallel.
1500 Vrms, one minute isolation (hipot) from primary to secondary.
