Re: Identifying capacitor type - Older 2002 videocard
I don't know how you identified this datasheet (I didn't even know what NA was), but that's exactly what I was looking for, and more. Thank you!...

Identifying capacitor type - Older 2002 videocard
Not good at identifying caps - 180uF in what Voltage/cap type? Card boots, but I saw that one leg was broken and have pulled the other one off for replacement (top/left of photo). Radeon AIW 9700 Pro.
My uneducated guess is 180uF SMD aluminum electrolytic of maybe 16V, since the card pulls from the 4-pin floppy connector. Lower Voltage? I see the 10V cap over to the right, so perhaps that one is being used for input Voltage of 5V, not pulling from the 12V pin?

Re: Identifying reason for board's similar caps, but different physical sizes
Yeah, I don't want this nas setup much longer - I've outgrown it, but want to keep a compact, quiet, non-rackmount setup. I'm waiting for U-NAS products to come back in stock so I can swap up to an 8-bay with user-selectable psu, rather than external brick using 4-pin mini-DIN, and then this DC-DC board inside the case.
The board sits just under the backplane, so cap height is an issue in a couple spots. 16V 1500uF would fit in there....Leave a comment:

Re: Identifying reason for board's similar caps, but different physical sizes
Thanks - I will continue to run it as-repaired with my Nichicons. My NAS has been down since October, relying only on manual backups since then. The automated full backup started this morning is running great.Leave a comment:

Re: Identifying reason for board's similar caps, but different physical sizes
The others don't say anything more than what I took photos of.
I went and replaced all the caps with my Nichicons and the system is working again. I didn't differentiate between the two different 1000uF.
Still curious what the difference could be though, being that the only difference is that the blue-green ones were on the 12v circuit....Leave a comment:

Identifying reason for board's similar caps, but different physical sizes
I have this board which converts 19V to PC Voltages:
The green and purple capacitors have the same Voltage, capacitance, and temperature ratings. The purple caps are smaller than the blue-green (more greenish in person).
The blue-green caps are used on the 12V section:
I can't find anything online about these capacitors. Is there any reason the 12V section would be using different capacitors, when the primary specs are identical?
Just need to see if I can use the Nichicon 1000uF...Last edited by Masejoer; 02-01-2020, 01:52 PM. -
Re: New Members - please post your introductions here
Here trying to find the difference between two caps with same basic specifications, but different heights, from the same brand, on the same board...Leave a comment:
