1. When ordering, specify a packaging code:
PA6384-ALD
Packaging: D = 13â³ machine ready reel. EIA-481 embossed plastic
tape.
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 Pri A measured on an Agilent/HP 4284 at 100 kHz,
0.1 Vrms, 0 Adc.
3. Leakage inductance measured between pins 1 and 4 at 100 kHz, 0.1 Vrms,
0 Adc with pins 2 and 3 connected and with secondary pins shorted.
4. DCR for the scondary is for each winding.
5. Turns ratio is with the primary windings and secondary windings connected
in series.
6. Electrical specifications at 25°C.
Refer to Doc 362 âSoldering Surface Mount Componentsâ before soldering.
