There's a 47nF ceramic in parallel already. To lower the cost I can
increase the R in the filter so I need a smaller C. Probably will switch
to tantalum. In the overall scheme of things it's not a big cost, but the
voltage being detected and compared by the PIC is an important
part of the s/w, and all being well I'd like to see the units run for many
trouble-free years. Normally I'd have not worried about it, as Spehro
suggested, but I just happened to come across a web page the other
day that traced faulty operation of a piece of equipment to electrolytic
caps de-forming
