Coilcraft, Inc. Flyback Transformers for TI LM5072 PD Interface FA2900-AL FA2900-ALD

Flyback transformer designed for 25 W PoE applications with the Texas Instruments LM5072, providing a 12 V, 2.1 A output with primary windings connected in parallel. The component has a primary inductance of 50 µH, primary DCR of 20 mΩ, and leakage inductance of 315 µH. It features 1500 Vrms isolation between primary and secondary, an auxiliary winding output of 11 V at 20 mA, and operates over an input range of 18 to 57 V. The transformer is packaged in tape and reel with 175 units per 13-inch reel, uses ferrite core, has a weight of 13.6-13.9 g, and supports ambient temperatures from -40°C to +125°C. Terminations are RoHS compliant tin-silver over tin over nickel over phosphor bronze. It meets MSL 1 moisture sensitivity and withstands three reflows at 260°C for 40 seconds each.
