1. When ordering, please specify packaging code:
NA6223-ALD
Packaging:D=13″ machine-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 1 kHz, 0.5 Vrms, 0 Adc.

3. Peak primary current (1.1 A) drawn at minimum input voltage.
4. DCR for the primary is from pin 1 to pin 2.
5. Leakage inductance measured between pins 1 and 2 with all other
windings shorted.
6. Turns ratio is with the primary windings connected in series.
7. Output is between pins 7 and 10. Bias winding output is 10 V, 20 mA.
Sync winding output is a 5 V Sync FET gate drive signal.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
