Document 703-1 Shielded Coupled Inductors MSD1260T The MSD1260T series of shielded coupled inductors was designed specifically for high temperature applications up to 125C ambient. Tight coupling (k 0.97) and 500 Vrms isolation make them ideal for use in a variety of circuits including flyback, multi- output buck, SEPIC and Zeta. These parts provide high inductance, high efficiency and excellent current handling. They can also be used as two single inductors connected in series or parallel or as a common mode choke. + + D C V L1 L2 OUT C V IN SW Typical Flyback Converter + D V OUT C AUX 0.484 L2 max 12,3 ++ Dot indicates pin1 123 L1 0.484 Dash number V max V OUT D C IN 12,3 SW X Internal code Typical Buck Converter with auxiliary output D 0.236 0.008 ++ * 6,0 0,2 C1 L1 Recommended V C LandPattern V Q L2 C OUT IN 0.217 0.197 5,5 5,0 0.157 0.138 Typical SEPIC schematic 4,0 3,5 2 1 3 4 0.197 0.177 5,0 4,5 3 4 2 1 ++ L2 C1 Q V CCD OUT V L1 0.059 0.079 IN 1,5 2,0 For optional tin-lead and tin-silver-copper * terminations, dimensions are for the mounted Typical Zeta schematic part.Dimensions before mounting can be 1 2 an additional 0.012 inch (0,3 mm).
