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.

Operation under no-load conditions will not damage these devices; however
they may not meet all listed speci?cations.

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.
