Hi I agree. Tantalums have, in my experience only one advantage, size to capacitance ratio. When you take into consideration that most circuitry has lots of spare 'hidden' real estate (space that is unused) then it does not make sense to put in higher priced, less reliable components. Distributing the capacitance around in smaller units is invariably a better option. We will not get into the arguments about the strategic problems of sourcing raw tantalum ores, D.R.C. (Congo), coltan wars etc. On Tue, Feb 23, 2010 at 10:38 AM, Russell McMahon wrote: > > >Use solid Aluminum caps which are as good but don't have the problems > > what's the cost and size on solid aluminum caps?, e.g. "10uF, 25V", or > "47uF, 35V"? > > My recollection is that size and costare similar to tantaum. > A quick look at Digikey suggests otherwise BUT I doubt that what I am > seeing there is representative. > > A look through a suppliers list who sells them in volume would tell you. > > > > R > . > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
