1. When ordering, please specify packaging code:

PA6284-ALD

Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts

Dot above pin1

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.
