Broken Laptop SMD capacitor

[jadas]

I try to replace a broken smd capacitor from an Acer Aspire 5920 motherboard.

After searching I figured it is a tantalum smd capacitor. Here is an image:



( Letters were not very clear so I used Paint )

Could you please help me identify it? I suppose 470 means 470uF , but what 70Dt stands for?

Thanks in advance,
Jadas.

Yes it is 470uF. I think 70Dt is simply a manufacturing date. Where is it located? It could be either 6.3v, 16v of 25v depending on the circuit - use a lower voltage cap and it will blow up, while a higher voltage one may not physically fit.

"D" is 20V rated.

Thanks for both answers.

tom66 : Did you identify the model ? Could you tell me where did you find that info, in case something breaks again?

Re: Broken Laptop SMD capacitor

After some more searching I found out that capacitors are marked with capacitance in pF,
but if that was the case here we would have 47*10^0 pF which I dont think it is manufactured. So it can only be 470uF ?
Also the only thing that could relate with Voltage would be the letter D.
So my only choice would be a 470uF , 20V capacitor ?

Please correct me if I'm wrong.
