The SRF1280-330M is a dual-winding shielded power inductor from Bourns' SRF1280 series, offering flexible parallel and series inductance configurations for diverse power conversion topologies. In parallel configuration, it provides 33 µH inductance (±20% tolerance) with a maximum DC resistance of 0.0664 O and rated RMS current of 3.23 A, while the series configuration delivers 132 µH inductance with 0.265 O maximum DC resistance and 1.61 A rated current. The component features magnetically shielded construction with low radiation, ferrite core, enameled copper wire, and operates reliably across -40°C to +105°C with a temperature rise of 40°C at rated current. It is well-suited for SEPIC topology converters and power supplies in communication equipment, computing systems, LCD backlights, and consumer electronics, offering the flexibility of dual-winding configuration for both series and parallel applications.
