1. When ordering, please specify packaging code:  
FA2925-ALD  
Packaging: D = 13machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel).  
B = Less than full reel. In tape, but not machine ready. To have a leader and trailer  
added ($25 charge), use code letter D instead.  
2. Inductance is for the primary, measured at 200 kHz, 0.2 Vrms, 0 Adc.  
3. Ipk is peak primary current drawn at minimum input voltage.  
4. DCR for the secondary is per winding.  
Dot above pin1  
5. Leakage inductance measured between pins 1 and 2 with all secondary pins shorted.  
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.
