SMT PoE Transformer

This series of transformers is designed specifically for

PoweredDevices(PD)inIEEE802.3af-compliantPower

over Ethernet (PoE) applications.

They feature interleaved primary and secondary wind-

ings to minimize leakage inductance, and a separate

bias winding. Isolation is 1500 Vrms between the

primary and secondary windings.

Coilcraft’s PoE transformers are available in 6 Watt and

13 Watt output versions for a 250 kHz switching fre-

quency. Input is 36 – 72 Volt and the output of the bias

winding is 12 V, 0.2 A.

Thesepartscanbeorderedwithleadscoatedinlead-free

solder that make them compliant with RoHS standards.

Coilcraft can also custom engineer a transformer to

meet your specific requirements.

Coilcraft Designer’s Kit C172 contains samples of all parts.

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.

Primary

When ordering a RoHS-compliant part, add an “L” before the packaging

code: e.g. POE13F-12LD

2. Inductance is measured at 250 kHz, 0.3 Vrms.

3. Peak primary current drawn at minimum input voltage.

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

winding shorted.

Bias

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

6. Electrical specifications at 25°C.
