For high temperature  
Coupled Inductors MSD1278T applications  
The MSD1278T series of shielded coupled inductors was  
designed specifically for high temperature applications –  
up to 125°C ambient.  
Tight coupling (k 0.98) and 500 V isolation make them  
ideal for use in a variety of circuits including flyback, multi-  
output buck, SEPIC and Zeta. These parts provide high  
inductance, high efficiency and excellent current handling.  
They can also be used as two single inductors connected  
in series or parallel or as a common mode choke.
