Hello All,
I am selecting a capacitor for smoothing and buffering rectified DC voltage fluctuation, and looking at different types of capacitors I have questions. Digikey.com has many to choose from and I was mainly looking at aluminum electrolytic capacitors. I noticed that the electrolytic ones have a lifetime rating where other types do not list a lifetime. Most electrolytic capacitors show around 2000 hours @ given temp. although they do go higher.
The question being: is there any advantage to using another type of capacitor than electrolytic for what I need it for? Do these other materials have a longer life? some of them do not list a (lifetime) rating.
I know what values I need, but Digikey has ceramic, mica, tantalum, film, silicon, etc..
Too many options
