Big, "computer grade" electrolytics generally have a long life. One possible
reason for a short life is running at high temperature, or running with
high ripple current. Computer-Grade caps are the ones with 10-32
screws on the top. I have used 30+ year old caps with brand names
like GE, Sangamo, Sprague, etc. with no surprises at all. Smaller,
wire-leaded caps mounted on circuit boards, and parts salvaged
from consumer-grade appliances are likely not made to the same
quality standards. If there's a good electronic surplus store in your
area, they should have a bin of these to fish through.
