1. When ordering, please specify packaging code:
PA6284-ALD
Packaging: D = 13â³ 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 measured at 100 kHz, 1.0 Vrms, 0 Adc.
3. DCR for the secondary is with windings connected in parallel.
4. Leakage inductance is for the primary and is measured with the secondary shorted.
5. Output is of the secondary winding. Aux winding output is 20 V, 10 mA.
6. Electrical specifications at 25°C.
Refer to Doc 362 âSoldering Surface Mount Componentsâ before soldering.
