    Dell Dimension 8300

    I have a Dell Dimension 8300 bought on 21 August 2003 in UK.
    The six caps near the CPU are 820uF, 6.3V, 8mm diameter x 20mm length. They are Nichicon HN(M). They have all bulged and some have leaked.

    I cannot find any specification on the Nichicon caps. But for replacement, I have bought, Panasonic, EEUFM0J821L. 820uF, 6.3V, 8mm diameter x 15mm length., Impedance/100kHz = 0.041Ohms, ripple current =1240mA.rms/100kHZ. Will these be suitable replacements?

    The other caps on the board which physically look are :
    3, 1000uF, 10V, 10mm dia. x 15mm length
    6, 220uF, 25V, 8mm dia. x 12mm length
    5, 470uF, 16V, 8mm dia x 12mm length
    4, 1200uF, 16V, 10mm dia x 25mm length
    Is it necessary to replace these also?

    Also I would like to know if there will be any problems if I leave the CPU and the battery on the board while replacing the caps.

    the EEUFM0J821L should be fine.
    personally i would remove the cpu and ram when recapping, the battery i would leave

    The other caps on the board which physically look are :
    3, 1000uF, 10V, 10mm dia. x 15mm length
    6, 220uF, 25V, 8mm dia. x 12mm length
    5, 470uF, 16V, 8mm dia x 12mm length
    4, 1200uF, 16V, 10mm dia x 25mm length
    Is it necessary to replace these also?
    we need the brand and series to tell you.

      Thank you for your quick reply.
      All the caps are Nichicon. I may be wrong abou the actual quantities.

      3, 1000uF 10V, PW(M) 105deg. C - dark brown with grey strip
      7, 220uF 25V, VR(M) 85 deg. C - black with grey strip
      3, 470uF, 16V, VR(M) 85deg. C
      4, 1200uF 16V, KZE, (H)105 deg C - Black with grey strip

      I did not like to remove the CPU as I am afriad I might damage the pins when putting back since I have never inserted one with so many pins. But may pick courage to remove it.

          Hi,
          Old post I know but the Pana part number returned this thread.
          Are those Panasonic caps suitable replacements for KZG series?
          Someone asked me to recap a board because I've used a soldering iron before!
          That's as far as their theory went on it...
          The board is an ASUS A8N-SLI SE with 4x 820uf 6.3v KZG bulging.
          I've pulled them already and the only other markings are (M105c) 6(k) 2b (one is 2w not 2b).
          I am not sure what the second set of numbers mean though... 6(k) 2b/2w, if they are relevant to me.. (m105c) is pretty self explanatory.
          Thanks in advance

            Panasonic FM is a liittle too high in ESR for KZG replacement.

            UCC KZG 820uf 6.3v 8mm x 11.5mm = .036 ohm ESR, 1.14A ripple current.
            Panny FM 820uf 6.3v 8mm x 15mm = .041ohm ESR, 1.24A ripple current

            You want to use Rubycon MBZ or MCZ, or Nichicon HM, HN, or HZ series.

            You can get Nichicon HN right here:

            https://www.badcaps.net/store/produc...roducts_id=163

            Nichcicon HN 820uf 6.3v 8mm x 11.5mm = .021 ohm ESR, 1.3A ripple current.

            You always want to use caps with the same or lower ESR, and the same or higher ripple current rating.

            The second set of characters is the date and batch code.
