Coilcraft has introduced its new PoE120PL Series of high-efficiency planar transformers which are optimized for active-clamp forward converters, including use in Power over Ethernet PSE and pre-standard PD devices. The PoE120PL Series is suitable for 60- to 120-Watt applications such as thin clients, monitors, industrial Ethernet, IPTV, building management, nurse call systems, point-of-sale terminals and information kiosks. They are well-suited for 90-Watt PoE++ Powered Devices (PDs).

PoE120PL SeriesPoE120PL Series transformers are optimized for 200kHz, with a 36- to 72-Volt input. They offer excellent DCR for high efficiency and very low leakage inductance. They also provide 1500Vrms primary-to-secondary isolation and 0.009 inch (0.229 mm) clearance above the seating plane and include a 12-Volt auxiliary winding.
