Hi, I was just curious if the brand of solid capacitors mattered as much as it did for electrolytic capacitors and if solid caps last a long time in general if they're used in things like motherboards and graphics cards.

Average lifespan of a polymer capacitor?

Re: Average lifespan of a polymer capacitor?
Depends which...
There are different kinds of polymers... If your thinking about Ultra-Low ESR polymers, there are two varieties, both of which should last well over several thousand hours, one more significantly longer than the other."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

In solid caps, stick with Rubycon, Panasonic, Nippon Chemi-Con, Fujitsu, and Nichicon__________________

and they dont just die at the end they just go out of spec.

Any cap misused or abused will fail, but for a general standard (used correctly in the circuit) Polys will last longer than Electrolytic only because they are designed to do so.Last edited by brethin; 09-30-2013, 08:06 PM.

but in reality, the brand of car and capacitor you buy has everything to do with reliability and durability!
There are Lexus's, Hondas, Subarus, Acuras, Toyotas and Infinitis at one extreme if you like to never see your mechanic, and Dodge, Ford, Land Rover, Jaguar and Chrysler's for you folks who like to have your car fixed on a regular basis.
In the capacitor world, pretty much the same story, just a different set of Japanese names at the top! - and as far "paying more"? - I don't think that 10 cents for the finest low-ESR 10uF 50V cap made is gonna break me, ya see, I've got that kinda cash!Last edited by theOracle; 10-01-2013, 12:01 AM.__________________

Re: Average lifespan of a polymer capacitor?
I only use Japanese and Korean capacitors.
favorite Korean brand is Samyoung
some other great Japanese electrolytic brands not mentioned in my previous posts are Toshin Kogyo, ELNA, and HitachiLast edited by theOracle; 10-03-2013, 02:18 AM.__________________
