120W Planar Transformers Optimized for Active Clamp Forward Topology

Cary, IL, -- Coilcraft introduces the PoE120PL Series 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 60-120 Watt applications such as thin clients, monitors, industrial Ethernet, IPTV, building management, nurse call systems, point-of-sale terminals and information kiosks. They are ideal for 90 Watt PoE++ Powered Devices (PDs).

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

PoE120PL Series transformers have a 20.83 x 23.37 mm footprint, with a maximum height of 10.34 mm, requiring far less board space and overall volume than a standard EFD20 wire wound package. They are RoHS compliant and feature matte tin over nickel over brass terminations. They have an ambient temperature range of -40°C to +125°C.

As with all Coilcraft parts, complete technical specifications and free evaluation samples of the PoE120PL Series are available online at http://www.coilcraft.com/poe120pl.cfm
