1. When ordering, please specify packaging code:
POE30P-12LD
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 the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc.
3. Ipk is 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 all other 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 âSoldering Surface Mount Componentsâ before soldering.
