The GOOD Capacitors Thread!!

[robert]

These new Panasonic series seem to be interesting...

Here, FJ and FJS mixed at the output, with FL on the Input.

Looks like FJ = FJS ?

Asus MB, survived a Tagan PSU (bad caps, as usual) and still okay. It was much dirtier before using 10bar compressed air
As ususal for Asus, they went cheap and saved quite a lot of parts...
Surprisingly, all smaller caps are FJ 820/6.3 (no OST!) but since its an asus, they somehow HAD to include some crap: a few small GSC (yeah! good old GSC, worst sh...t ever) as coupling caps for the sound chip (where they cant do damage)...

No one really knows for sure.
Panny didn't publish data sheets.

Is WIMA good?

[timarlop]

Are Elna REJ good replacements for teapos?

PSU: thermaltake w0009 420w

blue rail: Teapo sek 470uF 16v
purple rail: Teapo sek 470uF 16v


or should I use Nichicon PW Series 16V 680UF?

They're a German cap manufacturer the only place I've run into them is in old Grundig tube radios.

I'd be willing to say if they do manufacture lytics they would only be General Purpose.

WIMA?
They only make plastic film and paper capacitors for many years, they did make electrolytics long time ago though.
I saw a few WIMA electrolytics in an old Telefunken tape recorder, which is, guessing from the tube date codes, built in 1962. Still okay, apart from the faulty drivebelt (impossible to obtain).

WIMA film and paper caps are the best quality on the market, german made and very robust.
Their metallized paper X and Y RFI caps are best choice, never saw any one faulty. Most other brands of RFI caps fail every now and then in industrial environments from overvoltage spikes (theres also the infamous RIFA PME series, which had a few years of bad ones, that often failed with some years of delay, sometimes catching fire. However, RIFA PME is fine since at least 10 years, same bad batch thing as Nichicon HM)

[PCBONEZ]

If the WIMA lytics are that old they may have dry-out issues but otherwise it sounds like they are good caps.

I don't have data sheets available right now but I'd guess REJ is fine to replace SEK.

The Elna "price inflation" led me to choose the Nichicon PWs.

Found the REJ datasheet anyway, but can't see it with my pdf viewer.

Probable addition:
Panasonic Series FR
105°, Low ESR (comparable to FM series)
Long life (6.000-10.000h), longer then FM
Farnell lists them as new product and not yet in stock, but prices are surprisingly (for farnell!) good, somewhat below FM series.
http://www.farnell.com/datasheets/535408.pdf (Datasheet)

Panasonic Series FK
105°, Low ESR (between FC and FM Series)
2.000-6.000hrs Life
Very small sizes (4700u 16V in 12.5mm, for Power Supplies like Enermax where a 16mm part will not fit) avialible in stock from farnell!

Hi I need to replace some caps on my Abit NF7-s rev 2.0 I got 2 rubycon near the cpu which have it's top almost bumping.. they did not explode. (seems strange to me cause rubycons are good quality right?) .
However here in my country I can only get these caps

- Jackcon LOW ESR
- Panasonic FC ( problem is are these pannys LOW ESR? , can I fit them where the rubycons were?

these are the pannys I can get , are both of them LOW ESR? are they going to work fine ..?

thanks so much for all your help !

[dssence]

I forgot to add , I can also get this nichicon PS series ( I know PM, PW, HE, HD, HV, HM, HN,HZ are good caps but no clue on PS series )

http://int.rsdelivers.com/product/ni...f/5193898.aspx

thanks once more

[ratdude747]

easy question:

the panasonic fc is one of the best you can get... very low esr, very good quality... get that!

the nichicon might be ok... idk if it is low esr or general purpose.

jackcon sucks. really bad. one of the worst.

FC is NOT "very" low ESR.
They have about the highest ESR in the low ESR range.

whoops. i see my mistake... wrong panny series

[dssence]

Hi PCBONEZ , So should I get the panny FM series instead or the nichicon PS series these are the specs for both. Nichicon says in the specs it's LOW ESR but I read about it being low impedance same goes with panny, so I'm confused. Can you help me out on that.
I need to replace the rubycons 3300uf x 6.3 but I can get these only.

ESR is a component of Impedance and at the 100kHz they rate caps at the other components contribute so little to total Impedance that basically ESR = Impedance.
Give this a read:
http://www.badcaps.net/forum/showthread.php?t=10764

Series : Ripple / ESR
PS : 1280 / .075
FM : 2600 / .018
MBZ : 2800 / .012

PS aren't rated anywhere near where you need to be.
FM ~might~ last a while but they are under rated too.
I would hold out for Rubycon MBZ, MCZ or Panasonic FJ, FL or Sanyo WG.

[I'm assuming you aren't in the US because you are looking at RS's stock.]

[dssence]

Hi Bonez thanks for answering, so to be short ESR has to do with frequency and impedance but mostly impedance?. Well to be honest in the meantime I did buy some jackcon caps (a local electronics shop had these ones by miracle) which are low ESR I know they're marked as crap, but let's hope they work. I read the story about a user replacing lot;s of jackcon blown caps and jackcon sent him like 600 caps.. anyways I hope they did improve their quality. They have these markings in three different lines

02 02 02
09B 09B 09B
LOW LOW LOW
ESR ESR ESR

I think someone said to check those numbers and have to do with the manufacturin date.. hope these ones are fine..
So bonez yep I'm outside the US , they local retailer here buys from RS so thats my only choice which one will you go with between the nichicon and panny from those links I got no choice than getting those ones.
Thanks!

[PCBONEZ]

I've never been very good at short...

ESR is part of Impedance.
As Frequency changes ESR, XL [ESL] and XC all change too [in different directions] and all of them are part of total Impedance.

Terms like "low esr", "ultra low esr", "very low esr" are pretty much meaningless in so far as figuring out what is lower than what because there is no official standard definition of those terms.
Manufacturers call call them whatever they want.
Company 'A's "low esr" might be the same as company 'B's "ultra low esr".
To know what you are looking at you have to look in the data sheets.

As far as I know Jackcon are still junk.
I don't know their date code method because I just get rid of them anyway.

FM are better than PS.
If you are replacing MBZ/MCZ and they NEED to be that then FM are under rated for the application.

Hong Kong sends mail to everywhere on the planet.

I seem to be developing faith in Taicon electrolytics, since most of the series were the same (and some comparable) to the Nichicon units.
On a 9-year old board, none of the Taicon units were bulging...

Taicon is hit or miss. I've seen motherboards where every Taicon on the thing was bulged. So, unfortunately, it's not a reliable brand.
