The MSD1278T series consists of shielded coupled inductors designed for high-temperature applications up to 125°C ambient, with a winding-to-winding isolation of 500 Vrms and coupling coefficient of at least 0.98. The part is supplied in a surface-mount package measuring 12.3 mm × 12.3 mm × 7.8 mm, with a recommended land pattern of 5.0 mm × 5.5 mm. The MSD1278T-183 variant has an inductance of 18 µH ±20% per winding, a DC resistance of 0.080 Ω per winding, a saturation current of 6.50 A at 30% inductance drop, and a rated RMS current of 3.08 A for both windings. It complies with AEC-Q200 Grade 1 for automotive applications and supports operation from -40°C to +125°C ambient. The device offers a maximum part temperature of +165°C and meets MSL level 1 for moisture sensitivity. Packaging is provided on a 13-inch reel with 500 parts per reel in embossed plastic tape.
Coilcraft's MSD1278T Series of 1:1 high-temperature coupled power inductors are used in Flyback, SEPIC, Ćuk, Zeta and other applications. The MSD_T family features magnetic shielding for compact packaging and tight winding-to-winding coupling.
