“About codes for smd electrolytic capacitors, you inform that to read a capacitor of this model, just follow the table, and you give a legal example, Example: C475 means a 4.7 uF x 16 V capacitor since: 475 = 47 x 105 pF = 4.7 x 106 pF = 4.7 uF, well, I am in doubt, because I found a short on a notebook board, and it is precisely in a very small capacitor smd, I'm sending the image attachment, and from what I believe it is, it has the nomenclature C378 in table M, as can be seen too, my question is ... is this the correct way to know his reference on the board? C378, using your table will give 3.7 x 106 16V ... is that what I understand? Why did I think that this C378 would be the position of the capacitor on the board and we could only know the reference of it to be able to buy and make the exchange if we had the electrical scheme of the board ... take me out of this doubt please, thank you for your understanding, I admire your work a lot ”

 

Indeed, this is a problem that many have when trying to repair equipment. In some cases, as in yours, the smd component does not have its value marked on the enclosure, which would be valid. Many factories do not adopt this practice, and the components have no marked value. The value next to the component you see C378 is just the component's position in the schematic. In the same way as we make C1 = 100 nF in a scheme, we mark only C1 on the device and then we need to go to the scheme to find out that it is a 100 nF capacitor. Thus, only with the notebook layout is it possible to know how much is the indicated capacitor.
