1. When ordering, please specify termination and packaging codes:
2. Inductance is tested between pins 4 and 3 at 500 kHz, 0.5 Vrms, 0 Adc.
3. DCR is per winding.
4. Leakage inductance is for the primary with both windings connected in
5. Based on Bsat of the core at 25°C and number of turns on winding 4-3.
6. Calculated output power based on 150 kHz operating frequency. Power
7. Operating temperature range -40°C to +85°C.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
