... Filtering and Noise Reduction All A-Series UWR 14-20 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 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 ...
