The MSD1048 series comprises shielded, coupled power inductors with tight winding coupling (k ≥ 0.97) and 200 Vrms winding-to-winding isolation, designed for flyback, SEPIC, Ćuk, Zeta, and multi-output buck converters. The MSD1048-104 variant has a nominal inductance of 100 µH per winding, a maximum DCR of 0.387 Ω, a typical SRF of 7.3 MHz, and an Irms current rating of 0.85 A for both windings at a 40°C temperature rise. The device supports a maximum operating ambient temperature of +85°C with a maximum part temperature of +125°C. It is packaged in an 800-piece 13" reel with EIA-481 embossed plastic tape, measures 12.95 mm × 10.30 mm × 5.20 mm, and features a ferrite core with RoHS-compliant matte tin over nickel over phosphor bronze terminations. The component meets MSL 1 moisture sensitivity and withstands three reflow cycles at +260°C. It is qualified to AEC-Q200 and operates from −40°C to +85°C ambient.
Coilcraft's MSD1048 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.
