Ya, thats right I am so [H]ard I busted a capacitor... off of my video card. I couldnt solder it back cause one of the leads was broke very close to the insulator on the cap. Below is a copy of one of the 'intact' capacitors, it is identical to the one which was broken off. I cannot figure out how to decipher this type of cap. Could someone please decipher it for me. And tell me where I can find a replacement and also if any other type/size cap can be substituted.

TY, in advance.

The capacitor looks surface mount, and the image you have shown seems to sugest that it is 330u

a quick look on the internet told me that the middle number 330 is the capacitance (in u)

and i am guessing that it is 25v - the only reson for this is that most comonents are 25v and the 330u cap is only avalable in 25v.

i found the capacitor in the www.rapideletronics.com catalouge, part code 11-2314 but do a search on the internet for the manufactures code, which is DVCR33025

Ty for your help. Unfortunately the store you directed me to is in Colorado and I am in Massachusetts. I checked Radio Shack (they will be the closest to me) and the best I found was 470µF 35V 20% Radial-lead Electrolytic Capacitor. I take it that this should be sufficient for replacement? The voltage is higher but it should be backward compatible right? I dont remember much about caps.

im pretty sure that you will need a cap of the same voltage as this is part of the way they function. Cant remember much of the electronics course i did, it will come back to me soon

I am also fairly positive that the cap you linked to wont work.

It is going to allow 10 more volts run through the mobo, plus that 20% means that it can handle a 20% fluxuation in the voltage. So it can actually go:

35V x 20% = 7V up/down

That means that it will allow 17 more volts than the origional.

I would suggest looking for the exact one, even if you have to have it shipped..........I would rather pay $5 - $10 for the proper resistor than lose a mobo!

P.S. - I think I am correct, can't remember everything that i learned from my electronics course.

Yeah. When dealing with caps its best to get the same as replacements. Tolerances and nominal values will be different if you use a different cap, and may affect the way the circuit works to point that it may damage it, especially on something like a vid card that has close tolerances.

this may sound dumb or a spam..but like just call the company that made the card....they should know and hopefully will help you out...

I bought a 25v/330 capacitor... not the exact style replacement but it works 100%.

And it only cost me $1.53

I was just about to suggest to solder a wires to it's leads, solder those to the board, and use hot glue to hold the cap somewhere. But, your solution works, if you're into quick, cheap, and easy.

Click to expand...

The original cap had one of its leads broke off real close to the insulation on the cap. Trust me I tried many times. Eventually the only way to get a solid hold was to puddle a bit of solder on it. But that just made it hard to get anything on the longer lead. So I tried soldering the longer lead first... it ddnt work. This worked fine. Even though its not the same it works fine. I would show you my ghetto soldering skills but I dont wanna push my luck

sorry I lost the thred, but i am glad to see that your replacement works.

just to confirm, a higher voltage is fine, most capacitors are rated at 2x the voltage that ges through them anyway, so so using a cap rated at a higher voltage is fine

Ty 'The Overclocker' I used teh specs you agve me and as you see it works!
