Coupled Inductors MSD7342 ForFlyback,SEPIC,Zeta
and other Applications
• Tight coupling (k ≥ 0.97) and 200 V isolation make the MSD7342
series of coupled inductors ideal for use in a variety of circuits
including flyback, multi-output buck and SEPIC.
• They provide high inductance, high efficiency and excellent
current handling in a rugged, low cost part.
• Can also be used as two single inductors connected in series
or parallel, as a common mode choke or as a 1 : 1 transformer.
