Except for 3.3V devices which have no protection.
These power converters require a minimum 10% loading to maintain specified regulation.
Operation under no-load conditions will not damage these devices; however they may
not meet all listed specifications.
Application-specific input/output filtering can be recommended and perhaps added
internally upon request for scheduled, quantity orders. Contact DATEL Applications
Engineering for details.
Devices can be screened or modified for higher guaranteed isolation voltages.

Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating."
Designers will usually use the output Common (pin 5) as the ground/return
of the load circuit. You can, however, use the +Output (pin 3) as ground/
return to effectively reverse the output polarity.
Filtering and Noise Reduction
All A-Series UWR 6-10 Watt DC/DC Converters achieve their rated ripple
and noise specifications without the use of external input/output capaci-
tors. In critical applications, input/output ripple and noise may be further
reduced by installing electrolytic capacitors across the input terminals and/
or low-ESR tantalum or electrolytic capacitors across the output terminals.
The caps should be located as close to the power converters as possible.
Typical values are listed in the tables below. In many applications, using
values greater than those listed will yield better results.
In critical, space-sensitive applications, DATEL may be able to tailor the
internal input/output filtering of these units to meet your specific require-
ments.

may adversely affect long-term reliability. Proper operation under conditions other than
those listed in the Performance/Functional Specifications Table is not implied.
