Coupled Inductors– MSD1260 ForFlyback,SEPIC
and other Applications
• Tight coupling (k ≥ 0.98)
• 500 V isolation
• Ideal for use in a variety of circuits including flyback, multi-
output buck and SEPIC.
• High inductance, high efficiency and excellent current handling
• Can also be used as two single inductors connected in series
or parallel, as a common mode choke or as a 1 : 1 transformer.
