Hey all,

Friends system suddenly turned off, found out it was the g'card, had a look at it and i see one of the caps is broken, i pulled it off making sure the legs remained so i can repair it.. i need help recognising this cap tho...

pic of card: FX5900 Galaxy

the cap says on top...

2 2
220
1 6V

its gold.. i take it that 220 is 200MicraF ? 1 6V is 16V.. ? help please! :D

Yea, that looks like a 220uf, 16v capacitor. If you replace it, make sure you use a low ESR type capacitor

[mushk1n]

right, wots the 22? 2.2mA? ermmmm ? i wots ESR - electro static radiation?

cheers, need to be certain thats wot the numbers stand for...

[persivore]

the 22 will probably be some sort if ID for the part.
ESR is the effective series resistance of the capacitor. Most 'poor' quality capacitors will have a relitively high ESR, and could fail quite quickly under the conditions they are subjected to. You need to use a good quality capacitor with a low ESR as a replacement to avoid failure of the capacitor, and provide effective voltage smothing for the voltage regulators.
