No. Capacitance is reactive; as far as it is a good capacitor it doesn't dissipate power. Of course real parts have loss in the resistance of the leads, in the dielectric, etc. and do dissipate some small amount. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
