I recently came across a bunch of 25v & 50v caps of values of 10,000uf and 4700uf each (respectively). I have other caps that are of very similar ratings and they are 33-60% of the size of the ones I just received. These "new" caps are from equipment that isn't even 10 years old so I don't know if i t is because these are older and the manufacturing wasn't as good (thicker dialectic, insulator, etc). I've yet to take one apart but I intend to some time.
I've noticed different size caps before but nothing like the difference in these. The problem with these caps is that there isn't much information on them besides V & UF rating, They also say "TSHN, an "M" inside a squared circle, CE and +105C
I was wondering if caps like this that are so much physically larger have any benefits or if they might have something like a lower ESR or something. I've also seen mentioned that larger ones might have or allow for a higher ripple current?
Unfortunately I don't know what kind of equipment these were pulled from other than looking at the circuit boards and seeing the manufacturing date's of 2009 to 2013, so that's about all I have to go in. In addition, the caps were grouped in a set of 6, 2 25v in parallel, 2 50v in parallel and another 2 50v in parallel - and all the caps are identical in physical size, the 50v being about 30% heavier. I'm assuming it was done this was b/c of space considerations or maybe some benefit that larger caps don't have (like a lower total ESR when in parallel?
