I don't think that's the right question. Electrolytics come in thru-hole and SMT, as due tantalums. I assume that they have a mix of both electrolytic and tantalum. I know that the Town Car and Mark guys are having issues with electrolytic caps. I mostly use tantalums for bulk caps in my designs because of the age problem. Still, for the really big ones, the cost is just too high. On the other hand, the cost of ceramics in the 10 to 47uF range has gotten low enough to start using those where I would have put tantalums (usually because I already have a few in the switching power supplies anyway). It's easier to justify if it reduces the unique part count on the BOM.
I dont consider an smt an electrolytic,,it is not physically the same..never seen an smt wound with oil.
tants are regularly replaced with can's in old designs when they fail as a better option.
in low power a tant will suffice but you will find in most any PS's can's are used because of durability.
tho i must admit in most boards due to cost or by design they are underpowerd on purpose.
ceramics have their place but cant filter and hold a charge like a can.
the cost of any cap is now so cheap when replacing there is no reason not to go a bit more heavy duty.
typical TV PS cap,,16v,250uf ?? 25 cents for a 24v 450uf.
sure,,load up time may take take a couple milliseconds more but the end user wont notice .
reading your reply again,,why would you replace a tant with a ceramic ??
they do diff job ?
replace a tant with a can ok,,but not a ceramic.
" ceramics in the 10 to 47uF " ,, what voltage range you talking ??
and how would they....,,,
LOL !!!
Joe,,i wonder how many are reading saying WTH they talking about !!!
I think we should get back to what TR is failing and it's rating and what supports it.
it well could be one of the support components that is allowing the TR to fail ?? you think ?
