Coilcraft MSD1038V Series surface-mount 1:1 coupled power inductors feature higher isolation and are suitable for No-opto Isolated Flyback, Isolated Buck/Fly-BuckTM, SEPIC, Cuk, Zeta and other applications. Their compact, low-profile design and magnetic shielding make them ideal for a cost-effective alternative to custom core and bobbin transformers.
Electrical specifications at 25°C.
