1. When ordering, please specify packaging code:  
GA3372-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.  
Dot above pin1  
2. Inductance measured at 250 kHz, 0.7 Vrms, 0 Adc.  
3. Peak primary current drawn at minimum input voltage.  
4. DCR for the secondary is with windings connected in parallel.  
5. Leakage inductance is for the primary and is measured with the secondary shorted.  
6. Turns ratio is with the secondary windings connected in parallel.
