注释

Output is with the secondary windings connected in parallel. Output of the auxiliary winding is 12 V
When ordering, please specify packaging code: e.g. CX9642-ALD
Inductance is for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.
DCR is with the windings connected in parallel.
Leakage inductance is for the primary winding with the secondary windings shorted.
Turns ratio is with the primary and the secondary windings connected in parallel.
Isolation: 1500 Vrms one minute primary and auxiliary to secondary; 500 Vrms primary to auxiliary.
