Electrolytic caps typically have low lifespans compared to other types of caps, especially over larger temp ranges.. even with proper construction. When I use to do design for circuits that needed a long lifetime I would really question any use of electrolytic caps.

what would you use? tantalums? ive have the joy of recovering old equipment with dried tant caps on the power rails. (23 of 'em!) maybe tants are made better these days...

        sadly, this system is incompatible with 'noprocrastinate' :)

  In some cases you can use ceramic capacitors instead of electrolytic ones. I've done this exactly because I don't trust electrolytic capacitors to be anything more than big and cheap.

    for a PC switching power converters, such as in this article? sooo...where are you buying these mystical 2200uF ceramic caps? :)
