How do i identify capacitors?

Myronazz · Sep 20, 2017

Hello,

Someone really generous donated too motherboards to me, the first one is fine but the second
It has bulged and leaking capacitors, they leaked so badly i had to wash the board

I want to change them, though i have no idea how i can identify capacitors and find the right ones to replace them with

These capacitors right here leaked the most, they definitely need to be replaced

These ones didn't leak but some of them are little bulged, basically, i don't trust them

Fortunately, these black ones seem absolutely fine, their top is perfectly flat

So, how can i find the right ones i can use to replace them?

The blue ones look like 2200uF (micro Farad) 6.3 volt capacitors. You should be able to find them either online or in your local electronic supply store.
Do you have at least some soldering experience?

Once you have properly identified them you can buy at electronics components shop or search online.

if you have to ask that question, then think very carefully about whether you should do this. what other questions haven't you asked that are important?

I actually don't, but this is a nice opportunity to get some

since this is a socket 478 board, they can be found on ebay for less than 15$. so even if i damage it it's no big deal
Mostly, i'm doing this for the soldering experience and learning more about capacitors, even if i fix the board, i don't have a use for it

Then I would say "go for it". What have you got to lose?

If you cannot test the board how will you know that you have done it right?

Hint, them not falling off is not good enough to prove you've got it right.

I never said i have no way to test it, i said i don't have a use for it
i have a working Socket 478 machine i can test it with
