Flyback transformer designed for Microchip's grid-connected solar microinverter using dsPIC, supporting 220 Vac output with a turns ratio of 1:12. It operates with an input voltage range of 22 Vdc to 55 Vdc, features 3000 Vrms isolation between windings, and has a primary DCR maximum of 0.008 ohms and secondary DCR of 0.472 ohms. The part has a typical self-resonant frequency of 360 kHz, a saturation current of 10.5 A, and a primary inductance of 28 µH at 150 kHz. It uses ferrite core material, has RoHS tin-silver (96.5/3.5) over copper-plated steel wire terminations, weighs 94.3 g, and operates from -40°C to +85°C. It meets MSL level 1 and is packaged 20 per tray. Soldering resistance supports up to three 40-second reflows at +260°C with cooling between cycles. Certified for PCB washing per MIL-STD-202 Method 215 plus additional aqueous wash.
