The MSD1278 Series consists of shielded coupled inductors designed for flyback, SEPIC, buck, and Zeta converter applications, with a tight coupling coefficient of at least 0.98 and 500 Vrms winding-to-winding isolation. The MSD1278-154KLD part, rated at 150 µH ±10% with a DC resistance of 0.460 Ω per winding, has a saturation current of 2.8 A and an Irms of 0.91 A per winding, operating within an ambient temperature range of -40°C to +85°C. The device features a ferrite core, a maximum part temperature of +125°C, and is packaged in a 13-inch machine-ready reel with 500 units per reel. It meets AEC-Q200 Grade 3 (up to +85°C) and has a moisture sensitivity level of 1. Dimensions are 12.3 mm × 12.3 mm × 8.05 mm, and the termination is RoHS compliant matte tin over nickel over phosphor bronze.
Coilcraft's MSD1278 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.
