1. When ordering, please specify packaging code:
DA2316-AL
D
Packaging: D =13
″ machine-ready reel. EIA-481 embossed plastic
tape (200 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.
This flyback transformer is designed specifically for
powered devices (PD) in IEEE 802.3af-compliant Power
over Ethernet (PoE) applications.
It features an industry standard EP10 form factor, inter-
leaved primary and secondary windings to minimize
leakage inductance and a separate bias winding. Isola-
tion is 1500 Vrms between the primary and secondary
winding. Output of the bias winding is 8 V, 100 mA.
Coilcraft can also custom engineer a transformer to
meet your specific requirements.
Terminations:
Tin-silver over tin over nickel over phos bronze

2. Inductance 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. Operating temperature range –40°C to +85°C.
8. Electrical specifications at 25°C.
