1. When ordering, please specify packaging code:
DA2362-ALD
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 250 kHz, 0.2 Vrms, 0 Adc.
3. Peak primary current drawn at minimum input voltage.
4. DCR for the secondary is per winding.
5. Leakage inductance measured between pins 3 and 4 with secondary pins shorted.
6. Turns ratio is with the secondary windings connected in parallel.
7. Output of the secondary is with the windings connected in parallel. Bias winding output
is 12 V, 20 mA.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
