The MSD1514 series comprises 1:1 coupled inductors designed for flyback, SEPIC, Ćuk, and Zeta topologies, featuring high coupling coefficients (k ≥ 0.97), ferrite cores, and magnetic shielding for high-density mounting. The MSD1514-474KED variant has a 470 µH inductance per winding with ±10% tolerance, a DC resistance of 0.500 ohms typical, and a saturation current of 1.95 A at 30% inductance drop. It supports a maximum ambient temperature of +85°C with a 40°C temperature rise, and a maximum part temperature of +125°C. The component is rated for 500 Vrms winding-to-winding isolation, RoHS compliant, halogen free, and features matte tin over nickel over phosphor bronze terminations. It is packaged in 13" machine-ready reels with 175 parts per reel, and meets MSL level 1 for unlimited floor life at <30°C / 60% RH. Dimensions are 15.0±0.5 mm wide, 14.2 mm long, and 8.2 mm high.
Coilcraft's MSD1514 Series of 1:1 coupled power inductors feature magnetic shielding for compact packaging and tight winding-to-winding coupling. They are ideal for Flyback, SEPIC, Ćuk, Zeta and other applications.
