Floating Outputs
Since these are isolated DC/DC converters, their outputs are "fl oating."
Users may ground either the Common (pin 6) for normal usage or the posi-
tive side (+Output, pin 3) to effectively reverse the output polarity.
Filtering and Noise Reduction
All UWR 5 Watt DC/DC Converters achieve their rated ripple and noise
specifi cations without the use of external input/output capacitors. In criti-
cal applications, input/output ripple and noise may be further reduced by
installing low-ESR, tantalum or electrolytic capacitors across the input
and/or output terminals. The capacitors should be located as close to the
power converters as possible. Typical values are listed below. In many
applications, using values greater than those listed will yield better results.

Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For DATEL UWR
5 Watt DC/DC Converters, you should use fast-blow type fuses with values
no greater than 0.5A.

These are stress ratings. Exposure of devices to greater than any of these conditions
may adversely affect long-term reliability. Proper operation under conditions other than
those listed in the Performance/Functional Specifi cations Table is not implied.
