> >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.
