High inductance and high efficiency MSD1278-472ML_ Shielded Coupled Inductors
Description:
• Tight coupling (k ≥ 0.98) and 500 V isolation
• High inductance and high efficiency
• Excellent current handling
• Ideal for use in a variety of circuits including flyback, multi-output
buck, SEPIC and Zeta.
• Can also be used as two single inductors connected in series
or parallel or as a common mode choke.
