1. When ordering, please specify packaging code:
PA6340-ALD
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. Capacitance is measured from pins 1,2 to pins 6,10 at 250 kHz, 0.5 Vrms.
7. Turns ratio is with the primary windings connected in series.
8. 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.
9. Electrical specifications at 25°C.
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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
