Hi all, Remember that ESR is a resistance, so an easy way to reduce your resistance (and ripple current) is to put several smaller value capacitors in parralel, thus increasing your capacitance but more importantly DECREASING your resistance and ripple. Of course, space allowing! Regards Graham -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
