Tantalum capacitor

[Jeffro248]

I atempting to repair an automotive ECU and need some info on one capacitor in there. There are the numbers

476m
+10k

How many farads and how many volts is this?

thanks in advance!!

On small capacitors there tends to be a 3-digit code. In your case, it is 476. The first two digits are the value, and the third digit is the multiplier. The final value is in picofarads.

In order to determine the capacitance, simply multiply 47 times ten to the 6th power. Then convert from pico to (usually with these capacitors) micro or nano.

The 10 will likely be your voltage rating. I would think the "m" after the 476 is the tolerance. If I remember correctly, "m" means 20%, meaning it could be 20% above or below the given capacitance value.

Hope this helps!

I came up with 47 micro farads 10v. Does that sound right?

Yes.

Yep, sounds right to me!

Thanks for your help!!

this is formula to find out F = C/V,

this is formula to find out F = C/V,

Would you care to explain what the symbols mean, and how this short statement of yours contributes anything to this thread?
