    identifying smd capacitors

    I've got a LG 6871QYH039A y-sus board on which there are some coupling capacitors that I wrecked removing the ipm.

    The good ones that I didn't wreck show 0 resistance/inductance/capacitance on my component annalyser.

    Anyone know how I go about replacing them?

    Re: identifying smd capacitors

    Are you testing in or out of circuit?

    You'll most likely need to find a service manual with a parts list so you know what to buy.

    If you can't find one, post some photos of the thing. Someone may recognize the board and know what the components are.

      Need help identifying capacitors on an MSI MS6163 ver 1. motherboard
      by varkatope
      Hey there, retro fans.

      I have an MS6163 version 1 board I'm trying to repair which was obviously used as a donor because it's missing a few parts, mostly capacitors. There are few high quality images online that would allow me to read the capacitor values (bad angle, blurry photos). I thiiiink I've figured out most of the values for the missing ones except for one in particular, number C210, which is in the bottom-left of the attached photo. Could someone with this board be so kind as to take a look at theirs and tell me the capacitance and voltage values of all the highlighted missing...

      After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)
      by dragon3x
      Hi, I have some 32 bits computer motherboards that need repair, as they fail to
      power on.

      Here are some examples :

      (N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
      switching supply area).
      (N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
      than 6.3 V.)

      1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
      I replaced capacitors with aluminum-polymer.
      3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...

      AA and AAA battery charger capacitors?
      by slybunda
      hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
      it has inside:
      2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
      2 x 470uf 16v LZ105c branded as G.Luxon

      not heard of these brands are they any good?

      iv attached photos of the charger and the board inside for an idea on the type of...

      Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
      by sam_sam_sam
      I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

      This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

      After all of...

      Solar Inverter - SMH-II - 2 missing capacitors
      by Cama
      Hello,
      I need help to find the value of 2 missing capacitors ( C102 and C117) on my Easun SMH-II mainboard (solar hybrid inverter). I circled it in red on the close-up picture. The 2 old capacitors are completely missing, so I have no reference. Does anyone have this board and can tell me the value or make an educated guess based on the location ?


      My model is : EASUN SMH-II 7 KW
      Mother Board : P/N 18947-002401250250
      Maybe the EASUN SMH-II 4.2 KW have the same capacitors


      Thank you...
