SRF0703-221M is a dual-winding shielded power inductor from Bourns designed for multiple topologies including parallel, series, dual-inductor, and transformer configurations. In parallel mode, it provides 220 µH inductance (±20%) with a DC resistance of 1.48 O, rated current of 0.52 A (Irms), and saturation current of 0.53 A; in series mode, it delivers 880 µH inductance with 5.5 O DC resistance, 0.26 A rated current, and 0.27 A saturation current. The component features magnetically shielded construction for low radiation, operates across -40°C to +125°C, and is RoHS compliant. It is commonly used in SEPIC topology power supplies for communication equipment, notebooks, desktop computers, servers, LCDs, flat panels, backlights, camcorders, and HDTVs.
