I want to replace the caps on this mainboard but I'm not sure what to replace them with. I don't know enough about capacitance and am not sure where to turn for help.

Here's a picture. I don't know what the y2, x2, 2j and w4 represent. I'm assuming the next number is the microfarads and then the voltage. So on the one with the 2j for example... Don't know what 2j is, but does the 220 under it mean 220 microfarads? And then 4 volts? I'm finding all kinds of different kits but nothing with those exact numbers and letters. Can someone please help enlighten me on what I need to get to replace these caps? Thank you!!

    \$\begingroup\$ Why do you want to replace those capacitors? Unless you have a really good reason to think they are bad, I'd leave them alone. Bad aluminum electrolytic capacitors would have bulged or split lids. Those look fine. \$\endgroup\$ – JRE Jul 3 '19 at 5:15

i think X2 , y2 are just series or lot no it doesn't matter here

only capacitance and its voltage rating matters

  • \$\begingroup\$ Awesome Thank you very much! So I just go by the second and third numbers. So let's say the 'x2' one would be 330 microfarads and 4 volts? \$\endgroup\$ – Beauknowsdiddly Jul 3 '19 at 5:09
  • \$\begingroup\$ yes you have to buy 330uf 4V capacitor \$\endgroup\$ – Jay Vadoliya Jul 3 '19 at 5:15
  • \$\begingroup\$ updated image for better understanding \$\endgroup\$ – Jay Vadoliya Jul 3 '19 at 5:21
  • \$\begingroup\$ And that's the one I just can't seem to find of course. Would you happen to know of any kits anywhere that might have all those capacitors in it? \$\endgroup\$ – Beauknowsdiddly Jul 3 '19 at 5:21

    \$\begingroup\$ The series is important. Different series capacitors have different equivalent series resistance (ESR) ratings. Since those capacitors appear to be in a switching power supply, the ESR can make a big difference. Don't replace what ain't broke. \$\endgroup\$ – JRE Jul 3 '19 at 5:27
