Notes:  
1. From 5~100% load, nominal input, 20 MHz bandwidth oscilloscope, with 10 µF tantalum and 1 µF ceramic capacitors on the output. From 0~5% load, ripple and noise is  
<5% Vo.  
ꢀ. Measured at nominal input voltage, full load. The typical efficiencies for the chassis mount and DIN-rail mount versions are ~ꢀ% less than the board mount versions due  
to the input reverse polarity protection.  
ꢁ. All specifications are measured at Ta=ꢀ5°C, humidity < 75%, nominal input voltage, and rated output load unless otherwise specified.

APPLICATION CIRCUIT  
This series has been tested according to the following recommended circuits (Figures 1 & 2) before leaving the factory.  
If you want to further reduce the input and output ripple, you can increase the input and output capacitors or select  
capacitors of low equivalent impedance provided that the capacitance is less than the maximum capacitive load of the  
model.
