Thanks to everyone who contributed to this thread. Armed with this information I replaced the Siemens capacitor with a Rubycon 400MXG220MEF 2-pin item, and also replaced every electrolytic capacitor I could find with new ones of the same ratings as the old ones.
My reward for all this toil...
I notice that the tolerance for the KON22145 component is +/-20%, whereas the original capacitor is +50/-10%
Is this something I should be concerned about?
@davenn: Please see attached photo of the underside of the board the capacitor is soldered to.
@bertus: I'd be grateful if you would confirm that I've labelled the pinout correctly according to the PDF you kindly supplied. The solder pad in the middle of the terminals has no pin in it, so I'm...
@bertus:
Unfortunately the cap you mention is an axial component, and I require a radial one. It looks as though I'm going to have to bite the bullet and buy from the tedss.com site, delays and all.
@davenn: The cap is still on the board as I don't want to start removing components before I have replacements to hand, so pictures of the pin side aren't possible at present. I attach a picture of it in situ but I suspect that it won't add any new information.
@bertus: The picture you posted...
For me it isn't quite as simple as that, as the existing capacitor has multiple pins (four or five) and I lack the knowledge to determine which pins do what. I'm aware that two pins at least are probably there to support such a bulky package reliably, but which two?
As this capacitor is no...
Hello all
I'm new to this kind of thing, so please bear with my ignorance.
In order to avoid smoke-powered computing I'm replacing all the electrolytic capacitors in this 40-year-old PSU, as they seem to be originals. However, the biggest such capacitor in the PSU is proving very difficult to...
