Fake ELNA?

[Pentium4]

Found this in a Youngyear power supply. I broke the warranty seal so I know no one else messed with it. It seems very strange to see an ELNA in PSU, but also when the rest of the caps are Fuhjyyu, Koshin, GL, Su'scon, and Canicon.

I can find a RHS datasheet, but not RSH. And RHS only ranges from 160V to 450V

They are real

How do you know for certain?

Re: Fake ELNA?

Not a fake. I came across one of these in an "Ace Power" PSU, which is manufactured by "Pucka", but looks like Young Year inside (Yellow sleeved caps and green transformers. All the caps are yellow, except for the lone Elna RSH. Like you, it has a mix of Capxon Su'scon, and Fuhjyyu).




According to the spec sheet, this is 0.036 ESR, 1690 ripple, and 5000hrs. Not bad, maybe I'll reform it and use it sometime in the future. (And yes, that's a 1997 datecode).

Thanks for sharing. This is an Ace Power too it looks exactly like my Youngyear, are you sure it's made by Pucka? And interesting, I'd think a tall D12.5mm 3300uF cap would have more ripple current than that. Is that a 1997 date code?

Re: Fake ELNA?

It was made in 1997. It's more than what I would expect from a cap of that age

Yup:


I think Pucka and Young Year are the same company... I haven't seen "Young Year" printed on a PSU label for more than ten years... They're still using the old 5V rail heavy design though, even on these post 2005 Ace Power PSUs.

Mine is the 10V cap, yours is 16V. I can't find 16V 3300uF anywhere in the datasheet, but 16V 2700uF is over 2000mA, so this is a pretty decent, albeit unproven series. Would be nice to get my hands on a bunch of NOS of this though for bottom dollar.

Gotcha, couldn't really read the info from the picture. So yeah it has decent ripple current. Pretty sure these units are what's in all those Apevia units you see on Newegg. One thing I really like about Youngyear is they use massive transformers. ERL44 is pretty big, and I'm sure the switchers appreciate it. The heatsinks are weak though

Elna was a player in low ESR/Impedance lytics in the 1980s and 1990s, but not, IMO, first-tier (= "the four 'cons", Panasonic, Sprague, Mallory).

Re: Fake ELNA?

Elna RSH and RSE were high-endurance predecessors of RJH, RJJ, RJ3, RJ4 etc. They've been out of production for a while, IIRC.
