Panasonic FJ/FL genuine or not?

Re: Panasonic FJ/FL genuine or not?

Well, if these are not genuine caps, they are very very good counterfeits.

The print is slightly more clear on my caps, especially the negative strike. As such, the logo is a bit more clear too (and less horizontally stretched.) And the last discrepancy I found is that the degree symbol on mine is centered right between the "105" text and the "C" text, whereas on yours, it's a bit off-sided.

But apart from that, everything else looks the same - especially the voltage and capacitance text. So I think the differences I observed are probably due to slight variations in production. I've seen variations like these more than a few times from the other Japanese manufacturers too (particularly United Chemicon - which I've obtained all through Digikey or Mouser, so I know they should be genuine.) It all depends in what country and what factory they were made. My China-made Chemicons have quite a few differences from the Japan-made Chemicons. Nothing that pops at a glance, but if you look really really carefully, you will see it. I haven't had any problems with either of them, though.

Re: Panasonic FJ/FL genuine or not?

Thanks for that

I can't see any images in your posts. Please attach them to BCN forums, if you have any.

They were there... but maybe they disappeared because i didn't attach them, rather than just uploading them and inserting them into the post?
i have attached them now here:
So, now that thay are (hopefully) visible, does that logo the same as the one one yours?

Re: Panasonic FJ/FL genuine or not?

My XFX Radeon HD 4670 has *one* Panasonic FL cap, and it has a black sleeve with light gray (white?) text and negative stripe. 16V, 470 uF, 8x13 mm.

Correction:
It's Panasonic FJ

So does that mean that my caps are possibly legit? - Did the logo look like the one in my photos, and was the date code printed vertically like mine

But yes, your caps likely are legit. What Wester547 mentioned in post #18 might indeed be the reason why.

The date code on my one FJ cap is printed same direction as the text, and in the same plain white color as the text. Same with the Matsushita "M" logo.

I doubt mine is fake, because the rest of the board has Nichicon LF and OST OCRZ polymers that also look legit.

Just checked... and for once, my memory is serving me right.

Re: Panasonic FJ/FL genuine or not?

Will be interested to hear your findings; since i have not yet found any photos of an XFX Radeon HD 4670 with black/white FJ's.

Exact model number of the card is HD-456X-ZDFR, in case anyone wants to research for pictures.

Let this be a message to please upload the pics to Badcaps, in 10 cases out of 10 I never find the pictures after the host is gone.

Yup, I'll never use an external host ever again - at least for posting stuff on BCN. There were some old PSU threads where I replied and the pictures are now gone. It's a bummer, because for some of them, I invested a decent amount of time trying to help the O/P (and anyone else interested).

Also please consider donating to archive.org, it is a really fantastic service and I have lost count of how many times they have helped me!

It really is.
I can't believe I didn't know about it earlier. I think I found an OEM OS ISO I was looking for about 2 or 3 weeks ago and that's when I stumbled on archive.org. Surprised to see they have stuff hosted on their servers too.

Re: Panasonic FJ/FL genuine or not?

I managed to find the original pics on archive.org so now the original posts show them.

Re: Panasonic FJ/FL genuine or not?

Will do. Thanks.
i had a look through my cards, and found a 1000uf FJ on an RV2VE-B3; but it is black/gold with a red horizontal datecode (assuming that it's a date code).
i notice that on the logo of that capacitor, the M, that is inside the rounded square, is very well-defined and doesnt touch the rounded square like it does in the photos that i took.
This red-coloured date code is upsidedown and looks to be 1D IV (roman numerals)TV
The IVTV is aligned slighty higher than the 1D.
Will be interested to hear your findings; since i have not yet found any photos of an XFX Radeon HD 4670 with black/white FJ's.

Re: Panasonic FJ/FL genuine or not?

...Since i can't see the original photos, what are the odds that these capacitors (possibly from the same source) are not fake?:
i.e. is there any genuine black/white, (instead of black/gold) FJ's out there

Not sure, but I would have to dig out my XFX Radeon HD 4670 video card. It has black/white/gray Panny caps on it. Though they might be FR's, I can't remember.

If I don't reply, remind me again in a few days and I'll dig out that box that it's in. (I just don't feel like doing it right now, as it's close to midnight, lol. )

Re: Panasonic FJ/FL genuine or not?

so all electrolytic caps, that are "many years" old, should be thrown away?

no, but you shouldnt buy any,
and old stock may need to be re-formed.

i have had rubycon MCZ explode on me simply because a motherboard had not been powered for several years.
it slowly lost charge and depolarised in the box!

Re: Panasonic FJ/FL genuine or not?

I can't see the attachments. If they (the capacitors) are sourced from eBay and/or from Hong Kong, chances are they could be counterfeits. I've seen Panasonic FJ, FJS, and FL with black/white sleeves used on Pegatron motherboards manufactured after 2008/2009 or thereabouts. I suspect it was due to the switch from PVC to PET sleeves, as with the long discontinued Rubycon MBZ, MCZ, and MFZ series going from PVC blue/gold and black/gold sleeves to PET black/white sleeves.

Re: Panasonic FJ/FL genuine or not?

given neither have been made in many years - what does it matter?

They measure about 950uf and 0.11 ESR
(the apparent missing print on the last photo is only an illusion cased by the lighting)

Re: Panasonic FJ/FL genuine or not?

my 1000uF 6.3V looks similar like yours...
dissect one of it... the chemical colour looks correct...

Re: Panasonic FJ/FL genuine or not?

Of course. This is the voltage/capacitance picture. The pictures are mine.

Which seller did you order from?

Re: Panasonic FJ/FL genuine or not?

The mb is a Via P4PB-400.
I have changed CPU caps four years ago (replaced with Sanyo WG) and now I recapped the capacitors on 16 Volts line.

[momaka]

Re: Panasonic FJ/FL genuine or not?

they are certainly better than GSC (Great Sh*t Caps).

For sure

Mind if I ask what motherboard?

I just recapped a Jetway N2PAP-LITE about 2 weeks ago (also about 10 years old). Was full of GSC and they were all reading high capacitance on the ESR meter (meaning they have actually developed high internal leackage). Yes, every single one of them! And the really small ones were at least several Ohms ESR each.

Re: Panasonic FJ/FL genuine or not?

I welded these on my 10 years old motherboard, they are certainly better than GSC (Great Sh*t Caps).

[c_hegge]

Re: Panasonic FJ/FL genuine or not?

Yup. I've seen plenty of identical-looking Panny FJs on motherboards.
