The SD02S/D series are miniature, SMD Package, isolated 2W DC/DC converters with 1,500VDC isolation. The SD02S/D series 
features fully regulated output and wide 2:1 input voltage ranges. The most convenient advantage is the modules with a small 
footprint and low package height of 8.0 mm (0.31 inch) on the PCB.
 These isolated DC/DC converters are the latest offering from 
a world leader in power systems technology and manufacturing ― Delta Electronics, Inc.
