1. When ordering, please specify a packaging code:
PA6549-ALD
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (600 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 from pins 4 – 3 at 1 kHz, 0.1 Vrms.
3. DCR is for each winding of the primary and secondary.
4. Leakage inductance is for the primary windings, measured from pins 1 – 4
with all secondary windings shorted.
5. Based on Bsat of the core at 25°C and the number of turns on winding 4 ‑ 3.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
