Miniature Flyback Transformers for PoE

With a footprint roughly 16.5 mm square and with a

height less than 7.5 mm, these are very space-efficient

Power over Ethernet (PoE) transformers. They are

designed for 6 Watt, IEEE 802.3af-compliant applica-

tions for powered devices (PD).

These transformers feature interleaved primary and

secondary windings to minimize leakage inductance,

and a separate bias winding. Isolation is 1500 Vrms

between the primary and secondary windings.

There are versions for continuous and discontinuous

modes of operation, each designed to operate at a

250 kHz switching frequency. Input is 36 – 72 Volts and

the output of the bias winding is 12 V, 0.2 A.

Coilcraft Designer’s Kit C182 contains samples of all parts.

9,8

Secondary

11,10

5,4

Primary

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

tape (400 parts per full reel).

3,2

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.

Bias

2. Inductance is measured at 250 kHz, 0.5 Vrms.

3. Peak primary current drawn at minimum input voltage.

4. Leakage inductance is for the primary winding with the secondary

winding shorted.

5. Designed to remain in continuous mode operation at power levels of

3 Watts and above.

6. Operating temperature range –40°C to +125°C.

7. Electrical specifications at 25°C.
