But those on my boards seems to be of size 6.3x11.
So i have a question, do the "(IR) Ripple Current " value and "(Z) Impedance" value have to accurately match the original ones ?
I guess there is enough space available to replace them with the larger 8x12 but will it affect / degrade / damage the board ?1 Photo

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

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

If you search on the web site, Chinsan uses both 4.7 and 5 to refer to its 4.7 uF caps (and the usual 4R7 in parts numbers). 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.

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.

Given the age, if it is an electrolytic I'd suggest Nichicon PS, PM, PJ, or PW series, in that order of preference, whatever fits. I'm not sure whether polymer caps were coming into use in 1996.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

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.

Yes, Marcon (''N'') which is a diminutive of Marconi (in honor of Guglielmo Marconi, I suppose) and these are very old capacitors available in stores here in Italy in the era mentioned by PeteS in CA. They are still available as N.O.S. on some shops.
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.
