Anyone has any good replacements and sources in the US for a Sanyo OS-CON 2.2uF 25v Polymer cap? This is for a PC Power & Cooling Turbo-Cool Computer Power Supply. I noticed Panasonic adopted the OS-CON name but the lowest capacitance they make is 6.8uF, would this be a problem?

Re: Replacement polymer cap needed for Sanyo OS-CON 2.2uF 25v
Hm, interesting. Would be more expensive, but you could put 3 8.2uF polymer capacitors in series, to get about 2uF.
You might just be able to get away with using a regular electrolytic capacitor. 2.2uF seems too small to be a filter capacitor. Not sure why they would have used a polymer for a non-filter capacitor!

you may be able to use a ceramic these days.Comment

Re: Replacement polymer cap needed for Sanyo OS-CON 2.2uF 25v
If you go with a ceramic, use X7R, X8R, or COG, and a rated voltage 10X the circuit voltage (unless you have a COG part). If you use Y5V or Z5U and a rated voltage only double the circuit voltage, at operating temperature your "2.2uF" capacitor may be .47uF or less, due to the temperature and voltage coefficients of the ceramic material.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

The series idea might or might not work since how will I mount the capacitors? Also, by series, you basically mean you have 3 capacitors, and the - of cap 1 goes to 2 and then - from 2 goes to 3 and then 3 goes to the actual hole? Same thing with +.Comment

Hey all
I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...

a few days ago I finally purchased mser-100 v2 and I tested its abillity of measuring ESR value.
I found that It shows pretty accurate ESR value for electrolytic capacitor,But When I measure polymer capacitor of dreamcast game console,I found that one third of polymer capacitor's ESR value is more than twice the value of ESR meter table.(for example, I measured one polymer capacitor of 6.3v 100uf, It showed ESR value of 7.68)
Although my dreamcast now turns 20 years old but it still works. I occasionally have played game with it.
Is this ESR value of polymer capacitor correct?... -
i recapped the entire foxlink psu with rubycon caps of the exact uf needed. i also purchased a delta psu to see if the different brand would change anything and it did not. i recapped the entire motherboard except for about 5 of the 22uf caps. i used rubycon on everything except the five in front of the processors. i used 5 nichicon polymer caps there. i soldered a wire to each screw hole of the psu and soldered one wire to the metal outer shell and one to a screw hole on the motherboard(to make sure it was all grounded well). i also recently tried disconnecting the power cables from the dvd drive... -
"If I wanted to replace an old 15uF/400V capacitor with a new one,
I have a new 15uF/400V and a new 22uF/400V capacitor. When measured, the new 15uF reads only 13uF, and the 22uF reads only 20uF. Can I use the 22uF capacitor?" -
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.
