Coilcraft has developed a series of surface-mount transformers for IEEE-802.3af-compliant power-over-Ethernet (PoE) applications. These components feature interleaved primary and secondary windings to minimize leakage inductance and a separate bias winding. Available in 6-W and 13-W versions for a 250-kHz switching frequency, the transformers accept 36-V to 72-V input and produce 12 V and 0.2 A on the bias winding.
