1. When ordering, please specify packaging code:
2. Inductance is for the primary, measured at 400 kHz, 0.4 Vrms, 0 Adc.
3. Ipk is peak primary current drawn at minimum input voltage.
4. DCR for the secondary is per winding.
5. Leakage inductance measured between pins 2 and 3 with all secondary
6. Turns ratio is with the secondary windings connected in parallel.
7. Output is with the secondary windings connected in parallel.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
