Coilcraft has introduced its new PoE120PL series of high-efficiency planar transformers which are optimised for active clamp forward converters, including use in Power over Ethernet PSE and pre-standard PD devices. This series is suitable for 60-120 W 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 W PoE++ powered devices (PDs). These transformers are optimised for 200 kHz, with a 36-72 V input. They 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 V auxiliary winding. The 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° to +125°C.
