SRF1260-3R3Y is a dual-winding shielded power inductor from Bourns designed for flexible power supply topologies including SEPIC, parallel, series, and dual-inductor configurations. The device features a 3.3 µH inductance with ±30% tolerance in parallel mode and 13.2 µH in series mode, offering low DC resistance of 0.0101 O (parallel) and 0.0372 O (series) to minimize power losses. It supports rated currents up to 9.26 A in parallel mode and 4.63 A in series mode, with saturation currents of 12.7 A and 6.35 A respectively, and operates reliably across -40°C to +105°C. The magnetically shielded construction reduces radiation and makes it ideal for communication equipment, computing systems, LCD backlights, and consumer electronics requiring compact, efficient power conversion.
