Hi,
 
I have a broken Capacitor that I am looking to replace as one of the legs of the capacitor has come out of the capacitor.
I am lacking knowledge when it comes to knowing what I need to replace it. I am assuming that it needs to be the same cap for there to be no issues at all with the card and it be exactly how it should be?

It's for a PC sound card. A Creative Sound Blaster X-Fi Elite Pro 7.1 Channels 24-bit 192KHz PCI Interface Sound Card.

Here are some pictures of the capacitor (it's the large black cap)...

If anyone could please advise me to exactly what I would need to get to replace the cap, that would be great.
 
EDIT:
The broken cap is a G Luxon 220 16v (it also has some other info on it... 802P(M) )

Thank you!

The 220 is 220 uF (Micro Farads), which is a common value. check on Mouser for 220 uF capacitors, 16 Volts or better (the new one has to be at least 16V), but you don't need to go overboard. you should be able to find a cap with the same diameter(important if there are other parts nearby) and length (not as important, but may cause issues if it is too long and gets in the way of neighbouring boards), and lead spacing (important to be able to re-install the cap easily without bending the leads)
Also, I can't tell for sure, but it's likely a Polarized Electrolytic(the most common type of Electrolytic capacitor), meaning that there are a plus (+) and minus (-) lead, and the minus lead is designated by (-) signs on the yellow stripe (can't see them in the photo). It is critical that the new cap be placed back into the circuit the same way.

Hi,
 
The cap that has broken has a low ESR.
Is it not important to replace it with an equal or lower ESR cap?
Also, ripple.. should I not consider that?
 
I'm not sure how important it is on a sound card?
 
Is there any sound card modders out there that can advise?
 
thanks
