specially designed for applications where a  
group of polar power supplies are isolated from  
the input power supply in a distributed power  
supply system on a circuit board.

These products apply to:  
14  
1) Where the voltage of the input power supply  
is fixed (voltage variation ≤ ±10%);  
OUTPUT SPECIFICATIONS  
2) Where isolation is necessary between input  
and output (isolation voltage ≤1000VDC);  
3) Where the regulation of the output voltage  
and the output ripple noise are not  
demanding.
