Miniature Flyback Transformers for PoE
Document 402-1
Document 402-1 Revised 12/09/10
1. When ordering, please specify packaging code:
POE60D-12LD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (400 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, 0.5 Vrms.
3. Peak primary current drawn at minimum input voltage.
4. DCR for the primary and for the secondary are with the windings connected in parallel.
5. Leakage inductance is for the primary winding with the secondary winding shorted.
6. Turns ratios are with the primary and 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. Designed to remain in continuous mode operation at power levels of 3 Watts and above.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
