The new PoE120PL series of high-efficiency planar transformers made by Coilcraft are optimised for active clamp forward converters, including use in Power over Ethernet PSE and pre-standard PD devices. They are 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, and are ideal for 90 Watt PoE++ Powered Devices (PDs).
The transformers are optimised for 200 kHz, with a 36 – 72 V input, and offer excellent DCR for high efficiency and very low leakage inductance. They also provide 1500 Vrms primary-to-secondary isolation and 0,229 mm clearance above the seating plane and include a 12 Volt auxiliary winding.
With a 20,83 x 23,37 mm footprint and a maximum height of 10,34 mm, the parts require 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.
