    Low-voltage Capacitor Replacement in Laptops

    Hi everyone,

    I have got a general question about capacitor replacement which I faced in Laptop motherboards.
    Let us consider a smd ceramic capacitor connected to a 1.8-volt power or data or clock line. The capacitor is: 4.7uF_0603_6.3V
    The capacitor is supposed to work with low voltages such as 1.8v or 0.8v.
    Now, what will change in the circuit or laptop function if I replace that capacitor with a high-voltage smd ceramic capacitor such as: 4.7uF_0603_50V ?
    Does it matter whether it is connected to a power, data, or clock line?

      Does a 6.3v capacitor have better charging and discharging capabilities under low-voltages and high frequencies compared to a 50v capacitor of the same capacity?

          Is it possible to test small ceramic disc capacitor with analogue meter?
          by chth96
          I read EBOOK of Testing Electronic Component and found that

          "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
          Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
          It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

          Is it really possible to test small ceramic disc capacitor with analogue...

          Where can I get compatible capacitor for replacement?
          by artvandalai
          Blew the capacitor on my analytical balance scale using the wrong power adapter. I need help finding a replacement compatible capacitor to buy. Will any 100uf 40v capacitor work as a replacement?

          Samsung C32HG70 - Blown Ceramic Capacitor (CP813)
          by NuclearSpartan
          Hi everyone,

          I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.

          The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.

          I don't see any other visible damage anywhere else on the board....

          klipsch kda-500 amplifier suitable power supply capacitor replacement ?
          by r2digital
          I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...

          Discontinued Capacitor looking for Replacement
          by rwkish
          Capacitor has been discontinued (EGXF101ELL331MM20S) all of the replacements I have found have are smaller than 0.709" Dia (18.00mm). I would like to use the same size or at least close to the same size Capacitor. 19mm would be too big as they would touch and not be able to through hole mount. Tia...
