Coilcraft, Inc. MSD1278 Series Shielded Coupled Power Inductors MSD1278-334 MSD1278-334KLD

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.

• Ideal for Flyback, SEPIC, Ćuk, Zeta and other applications
• Magnetic shielding allows high-density mounting
• Tight winding coupling
• Industry standard footprint
• AEC-Q200 Grade 3 (−40°C to +85°C)

See Selecting inductors for SEPIC

Our MSD1278 Series common mode chokes provide both common-mode and differential-mode filtering in a single device. They are ideal for use in both power line and signal line applications, providing 500 Vrms, one minute winding-to-winding isolation.

• Common mode and differential mode filtering in a single device
• Ideal for use in both power line and signal line applications
• Up to 110 MHz differential mode cutoff frequency
• 500 Vrms, one minute winding-to-winding isolation
