PoE Transformer

–

DA2316-AL

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.

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.

1. When ordering, please specify packaging code:

DA23±6-ALD

Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic

5. Leakage inductance measured between pins 3 and 4 with all other pins

shorted.

tape (200 parts per full reel).

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.

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.
