    I also reinforce that, given their era, this is not a polymer. I would replace it with a Panasonic FC but also Nichicon PM would be perfect (E.S.R. not too low and capable of handling high frequencies). I would derate and use a 10V replacement.


    EDIT: I confirm, electrolytic. As per specifictions in the inventory of a shop which sells N.O.S. parts. Picture attached.
    Thanks Hitto & PeteS in CA!
    I'll be ordering some nice electrolytics as replacements.

    My bad, these are made by Marcon, ending with an "n". Marcon Electronics, a former subsidiary of Toshiba Corp, then bought up by United Chemi-Con.

    Thanks PeteS, that's what my friends in the SGI collector community have done. Then again, some have failed to repair their PSUs or had them fail after a recap. Most of us are flying "flying blind" tho as SGI never released any schematics.

    My PSU is working but outputting high ripple. It's very noticeable and was getting worse the more I used my machine, so I took it apart to fix the supply.
    This is the only one of three like it in the supply that tested bad with my LCR meter. The other caps in the PSU were getting old but in OK condition and within tolerances.

    Does anybody have any old Marcom data books or data sheets to confirm it's a polymer or what the CFM series was? I'd feel better replacing these three with a FP high ripple tolerant and super low ESR variant if that's what these are.

    Hey all. I'm recalpping an Artesyn P/N 22943505 PSU with SGI P/N 060-0021-002 Rev A for an Indigo2 IMPACT and have come across some bad caps that I can't identify a replacement for. They're red, very small, made by Marcom. I think they are FP-Caps (functional polymer/solid caps), but Marcom got bought up Nippon Chemi-Con a year before these caps were produced. They are 330uF, 6.3V, 105degC, red in color with a silver "-" stripe, 10x10mm and one of three on the board tested bad with an LCR meter. They are marked "CFM" (the series) and "9614" which I'm told is how Marcom prints the manuf. date of 1996 14th week.
    Let me know if you need a pic.

The link in the post above me will get you started on your long, long journey through the Chinsan parts list... it's just a standard low-impedance cap so there are a lot of alternatives.

    (Maybe that's a 47 and not a 4.7: the "." might be a reflection.)
    Thank you very much

    Anyone able to help fully identify this cap? Need to get a replacement. It was ripped off a Asus motherboard.

    Would like to know what ESR it needs for buying from Digikey/Farnell/Mouser etc.

    PC210 is 2200 pico farads , 0402 is the size , 25 Volts. You can find capacitor conversion charts online to convert between micro fardas uF , pico farads pF and nano farads nF .

    Hi,
    I'm trying to replace what seems to be a film(?) Epcos capacitors labeled with:
    Z111774865 P10
    U12 J 900 D8
    I'm guessing it's a 120nF 900V? But I would appreciate exact reference, because google doesn't find Z111774865 at all.
    They came from a Siemens induction heater, 3 of them are connected in parallel between the 2 wires that power individual induction segment.
    Their size is aprox. 26mmx15mmx7mm.
    Thanks for any help

    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...
