For Flyback, SEPIC  
and other Applications  
Coupled Inductors  
–
MSD7342  
• Tightcoupling(k≥0.97)and200VisolationmaketheMSD7342  
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.
