New Capacitors

[BustinCaps]

Hi All. So I am new to this forum and would appreciate your help in identifying some capacitors I ordered from Amazon.

I ordered them before really researching and finding more reputable resources like Digi-Key. The caps I originally ordered were Rubycon MCZ from the pictures shown. I later found out this was a bad move since these are outdated and have been heavily counterfeited. Much to my surprise, when the caps arrived they were not Rubycons but the ones shown in the pictures attached. Can anyone identity them and tell me if they look fake. Any help would be appreciated.

Matsushita-panasonic is the brand. Better IMHO. Though, they look fake too. The cropped leads are not promising either. Can't really read the other text.

Re: New Capacitors

Since Matsushita renamed itself to Panasonic Corporation, new Panasonic electrolytic capacitors no longer have the manufacturer's insignia - should Panasonic have an insignia for their components? I think so.

So if these are even genuine, are they old stock?

Re: New Capacitors

they *almost* look correct, they should have a "+" before the temperature - other than that they look right.
they are cropped because FL series are used on motherboards, but not AFAIK sold to the public.
so the leads will be cropped for pick-n-place machines.
that's also why you wont find a datasheet.

i would say they are surplus from a chinese or korean production line.
you should find a date printed on them lightly in red between the gold bits.

Re: New Capacitors

Looks like possibly a pull from a motherboard...

Re: New Capacitors

no, it's not been used, but i want to see the bung.

look at a real one i pulled.
i just pulled it from the spares rack & foto'd it.

Re: New Capacitors

OK there are 3 different markings on the caps. Most have what looks like 6DIVEF. There is also 5DIVUS and 6DIVEE. I hope you can see this from the attached pic.

So you think they are used and have been pulled from mb?

Re: New Capacitors

looking at an internal datasheet - they may be used / recovered from a board.
the FJ datasheet shows several lead types, but short & straight isnt one of them.

it's hard to say for sure though - what does the bung look like ??

Take a look.

If they are recovered from a board, then they did a good job because they look very clean. There are no scratches and none of the leads are bent in the least

Re: New Capacitors

well it's the right bung, so it's probably not fake.

Thanks for the info. I will probably keep them then.

Re: New Capacitors

cant help noticing the following issues with the TS' caps:

1. why is the bung purple/blue tinted?

2. the line used to draw the M logo is too thin.

3. the "105°C FL" font is too large compared to stj's genuine caps.

The bung is black. Probably just the lighting that makes it look a different color. There are differences in the print between caps labeled 6DIVEF and 5DIVUS. See pic below. 5DIVUS shown at the top..6DIVEF at the bottom. Font and logo size look different. Also, top cap has + before "105°CFL". Maybe different production runs. I don't know. If anyone has any further insight, it would be appreciated.

A snip from a Panasonic pdf from 2004, i think it was .

Looks like yours are supposed to be 4 week of dec, 2005 and 2006 .. or dec, 2015 and 2016 or afake date code.
Seems like December of 2015 is too fresh, and the ones from dec 2016 are even fresher
tomorrows product at todays pricing.
What's the top look like?

Re: New Capacitors

I think I have some 1800 uF 6.3V Panasonic FLs (pulled from a s478 -era HP board, so I know they are genuine). Will check them tomorrow to see what they look like. I think yours look pretty genuine, aside from the slightly larger Matsushita "M"-in-a-box logo. But it may be normal too. The bungs alone suggest these are genuine caps.

Good to know. Thanks for the feedback. Do you know if capacitors have a certain shelf life? If so what's the best way to store them so they last longer?
