The Good Capacitors Photo Thread

[willawake]

Everybody please contribute photos and explanation of the identifying marks of GOOD Low ESR capacitors for motherboard applications.

Aluminium Electrolytic Capacitors - Radial Lead


(Photo from Intel D875PBZLK motherboard, original caps)

Rubycon MCZ. A row of black with gold stripe Rubycon MCZ. Rubycon's top series






(Photo from an Asus TUSL2 motherboard, original caps)

Ruybycon MBZ. The dark purple cap indicated with the arrow. After MCZ they are the second best in Rubycon's series for motherboard applications because of their very low ESR. General availability is difficult. Topcat of these forums can sell you this range in 8mm sizes which are even more difficult to find.


(Photo from an Asus CUSL2-M motherboard, original caps)

Rubycon ZL. A very popular series for motherboard applications. Note the Black colour, The Rubycon K vent marking (many other companies use K markings though, note the style of the Rubycon K marking and that it is quite a deep thick cut unlike the counterfeit ones) also note the Rubycon logo and the cap range namely ZL is clearly noted. Along with Panasonic FC series, general availability is good. ZLH has longer life than ZL series though at the same ESR rating. ZA/ZLG series are the next step up in lower ESR than ZL/ZLH with ZLG having longer life than ZA.

Rubycon YXG. Same remarks as above, dark blue/purple colour instead. Not as good as ZL series but perfectly adequate also. YXH series has longer life than YXG though but with the same impedance specs.

Panasonic FC. Note the T vent marking which is exclusive to panasonic. Note the M character in a box which indicates Matsushita the parent company of the panasonic brand. Note the navy colour, they also come in black, note the gold negative stripe which is on both colours. Note the FC after the +105oC which indicates they are FC range. There is also FA series which is better but FC series is excellent for motherboard applications and general availability is good.

Polymer Capacitors - Radial Lead

Sanyo OS-CON Polymer capacitors : These do not have electrolyte they have polymerised organic semiconductor instead, so do not have the same failure problem. Therefore they do not have a vent on the top even though they are Low ESR. They are much more effective than electrolytic caps so you need lower values than before. Expensive caps.



Sanyo OS-CON SEPC Series. Sanyo's top polymer series typically found on vcore of high end boards or on graphics cards.


(Photo of HP serverboard from DL380G4 server, original caps)



Sanyo OS-CON SP Series. Note that they clearly say OSCON on them and the SP series is clearly indicated. The strange purple colour is exclusive to most of the series of OSCON caps. These are available in larger capacitance than SEPC but the ESR is higher though. The leads can be too big for the holes on some boards or graphics cards though.

Panasonic FM ones:

WARNING!!!

UCC KZG was later found out to be a BAD cap, along with UCC KZJ. They do not handle heat well and should ALWAYS be replaced. Lesson: component reliability is only proven after years of service.

United Chemicon KZG

United Chemicon LXY





They are not the lowest ESR on Chemicon Series caps, but suitable for PSU or VRM input. They have long endurance. For smaller size and almost same spec (almost same shiny color too), use Chemicon LXZ.

[trodas]

Nichicon HZ (top Nichicon model and by specs, far superior electrolyte cap ever) in my Sapphire "Grouper" A9RX480 mainboard









(the 3300uF 10V one is Nichicon HD one - still very good cap, yet HZ is the king of caps )

Nichicon HZ 1800uF 16V - impedance 0.006.5 - ripple current 4140 (2000 hours) 10x25
Nichicon HD 2200uF 16V - impedance 0.018 - ripple current 2770 (5000 hours) 12.5x25

Panasonic FJ Capacitor

For more than a year we had been questioning about its data specification. We see them in a lot of modern motherboards (even cheap board like ECS) and vga card (especially powercolor). Thanks to Willawake, he found the FJ datasheet that Panasonic it self hide it for no reason.

It turns out that this caps is for real, from Panasonic, and many motherboards/vga card manufacturers use it because it is comparable to: Chemicon KZG (good cap), Rubycon MBZ (good cap), Nichicon HM (it's badcaps in past time).

So if you found this FJ cap on a motherboard or vga card you want to choose, fear not, they are good caps.

So, performance grade of panasonic alumunium electrolytic capacitor series (lower to greater):


FC -> FK -> FJ -> FM

Nichicon PL and PM (1st pic)
Dark brown jacket with grey text, white datecode. Normal X-shaped vent.

Panasonic FK (2nd and 3rd pic)
Dark blue jacket with gold text, red datecode. T-shaped vent.

I use mostly Nichicon PL/PM but just got some Panasonic FKs for places requiring smaller can sizes.

Has anybody got a datasheet for leaded type Panasonic FK?

Here is the Panasonic FK Capacitor datasheet:

Nichicon PW








Nichicon PW is smaller than PL. In this picture, PW cap is in the middle.

(Same Sanyo WG caps but with different bungs, read here. Both are okay though.)

Panasonic HFQ

This series is used to be popular for audiophile. Now it is discontinued. Recommended replacement are Panasonic FC.

~ No ~

FM is less than Ruby MBZ
FJ is more than MBZ but less than MCZ

It goes:

FC -> FK -> FM -> FJ

I 'think' FL = FJ but I only have data on two sizes of FL.

these pics confirm the fj i have here are counterfeits.

Thanks I have the data sheets on file and I'm aware of what's in them:
You obviously haven't checked them because you are wrong.

Comparing same volt, uF, and can sizes:

FJ - 6.3v 1000uF 10x12.5 - 1540/.025
FM - 6.3v 1000uF 10x12.5 - 1290/.038
FJ has better the Ripple and ESR than FM.

FJ - 6.3v 3300uF 12.5x20 - 2800/.012
FM - 6.3v 1000uF 12.5x20 - 2600/.018
FJ has better the Ripple and ESR than FM.

FJ - 10v 1000uF 8x20 - 1870/.016
FM - 10v 1000uF 8x20 - 1560/.030
FJ has better the Ripple and ESR than FM.

FJ - 16v 1000uF 10x20 - 2550/.013
FM - 16v 1000uF 10x20 - 2180/.019
FJ has better the Ripple and ESR than FM.

This is 100% consistant.
The only time FM is better than FJ (for a given uF/v) is if the FM is in a bigger can.
- That's not the proper way to compare two series of capacitors.

So it's just as I said:

FC -> FK -> FM -> FJ

.

[PCBONEZ]

Correcting typo:

FJ - 6.3v 3300uF 12.5x20 - 2800/.012
FM - 6.3v 3300uF 12.5x20 - 2600/.018
FJ has better the Ripple and ESR than FM.

[yanz]

Heya PCBONEZ It's just that Ripple and ESR isn't the only things in my mind, FM series has far superior endurance..

But if we rule out the endurance than you're right. I guess, performance is performance and endurance is endurance. FC -> FK -> FM -> FJ it is. Like you said..

Any mods there, care to edit my post there? (change it to "FC -> FK -> FM -> FJ")
I really don't mind, thx in advance.
