Need help identifying capacitors
Posted by: eraser on 2010-07-22 16:48:24
Hi all.

I have a couple Macs with leaking capacitors that need to be replaced but I don't know exactly which capacitors I need. Hopefully some of you who have done this can help me out and we can figure out what I need and update the wiki for others who have these Macs as well.

I took some pictures of the capacitors for identifying the size/type and tried to also include the labels below because they aren't very easy to read in all the photos.

the 10, 47, 100, etc they are all values in microfarad.

the 16V is the voltage rating of the capacitor. so a cap that has a marking of 47 16v, would mean, 47uF 16V.

they are all surface mount aluminum electrolytics. If you dont feel to comfortable about the capacitors and being able to handle it on your own, get ahold of trag, im sure he will help you out.
