Solid capacitors?

neutron7 · 12th June 2007, 01:47 PM

I keep seeing on computer sites, mention of various motherboards using "solid capacitors" which are supposed to be better than regular electrolytics.

what are they? just electrolytic in a different package, or something new?

Thanks

They are aluminium electrolytics, but the electrolyte is an organic polymer that "sets" after filling the can, hence "solid". The main claim (from the PC world) seems to be longer life; in a motherboard that is probably obsolete after 3 years, is that really a selling point?

Gigabyte's snakeoil and the Dubilier claims, more focussed on lower ESR.

electrolytic capacitors failing are frequently the cause of motherboard problems. especially with some of the very cheap ones. anything they can do to increase the reliability of the capacitors over the life they are used for is a good thing.

now we just have to wait for some enterprising person to start slapping a 10,000% mark up on them and claiming wondrous sonic properties so we can use them.
