How long do electrolytic capacitors last in seldom-used …
As a rule of thumb life is halved for every 10°C temperature rise, so it''s usually good to buy 105°C-rated capacitors rather than 85°C, all other things being equal. The lifetime ratings at full temperature are very short (thousands of hours only). Higher voltage rating than the original is also better.
