And so I understand you have them in KZH?
If so then use them. - Good caps.

Re: Taicon HH replacement?
Be careful.
If you look closely they are probably not all in parallel.
They are probably part of PI filters and have coils in between.
Coils have such low resistance it can get missed by an ohm meter and the caps appear to be in parallel when they actually aren't.
Trace the circuit by eye-ball/hand.

Re: Taicon HH replacement?
The only 2200uF 16V 10mm capacitor I know of is the Panasonic FK...
Newark P/N: 32R8994
Wow, it was 109 yesterday, someone bought like 50 of them overnight... Be quick, they go like hotcakes.
PCBONEZ also mentioned that you can use a Samxon RS 16V 3300uF 10mm in it's stead.
PCBONEZ: I thought PI filters are always two caps input and one cap output?Comment

Re: Taicon HH replacement?
Nope, I've seen them done all three ways.
The first two are the most common by far.
The last one I'd have to call rare.
.
Technically they could flip the middle one [2 caps on output] and it's still a PI filter but I don't think I've ever seen that done.
It wouldn't make sense unless they needed really small caps on the OP end.
.
They are all better than the one coil one cap filters found in el'cheapo PSUs.

Re: Taicon HH replacement?
I did a cross-reference of Taicon and Nichicon electrolytics, and Nichicon HV has better ratings than Taicon HH.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

Re: Taicon HH replacement?
Are they 10mm?
I forget about that series. It's fairly new.

Re: Taicon HH replacement?
So, Nichicon HV comes in 10mm x 25mm for;
2200uF 10v
1800uF 16v
I wonder if 4x1800uF might be able to replace 4x2200uF. Aside from the uF, the ESR and ripple specs are a good match.
Or, if the 2200uF 10v might be able to handle 12v.Comment

Re: Taicon HH replacement?
No, never do that.
The voltage rating on the cap should always be at or above the actual circuit voltage.
In some cases you can lower uF but I'd rather not guess because I don't really know what you are working on.
In general it's not a good idea.
- It will change the frequency response of the circuit which may or may not matter depending on what it is.
- The uF is the characteristic that makes caps act like back-up batteries during transients like load changes or power line fluctuations.

Re: Taicon HH replacement?
It seems then I have but little choice except to use the original spec cap. The ones from that auction site (the worst place to get caps) came in the mail today. I'm really hoping they are unfake. If they are unfake, can anyone tell from the codes on these when they were manufactured. Thanks!Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: Taicon HH replacement?
The bung is firm.
I got them from auction. I'm glad they are probably good because I also got KZH 3300uF 10v in 10mm, which is also hard to find in 10mm.
While I enjoyed rebuilding this power supply, I think I wouldn't mind if I didn't repair another one for quite a while. Sourcing these parts, and all the soldering on this multi-layer board... it was all brutal and a quite a time suck.Comment

Re: Taicon HH replacement?
16V 2200uF and 10V 3300uF don't appear in the KZH datasheet at 10mm. Either they're a custom order part, or maybe not genuine...
Though if they really are a genuine custom order size, their ripple numbers look impressive, better than Samxon RS.
Expensive though, almost $2 a cap after shipping. Comparable Panasonic FK 16V 2200uF in 10mm is less than a dollar, though the stock doesn't last long.Comment

Re: Taicon HH replacement?
I've seen that size KZH in newer Antec EarthWatts PSUs. So, custom size. They certainly look like the real deal.Comment

Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -
Hi,
I was hoping to get some help in identifying a replacement capacitor for a PET Rubycon A0817 6.3V 1000uF rated for 105C temp, MBZ series.
This is to replace one bad capacitor on a DELL 530 motherboard DG33M03 (manufactured by Foxconn, DELL part # FM586).
I'm attaching the pictures of the bad cap.
Thank you so much!... -
Hello guys,
I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.
I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow... -
Hello,
Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.
So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.
I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,... -
i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...
