Nippon Chemicon W-Series?

[Stefan Payne]

I've seen the W-Series a couple of times now.
For example in the Seasonic Prime, here:

But does anyone have any data on this series?
Nippon doesn't seem to list them on their website.

"W" denotes a custom series made by Chemi-con at anyone's request. It's not a series which strictly conforms to one set of impedance or ripple ratings. It could be any custom series specified by the OEM under contract.

Great, just what we need!

Well, most caps in modern ATX PSUs are custom anyway, somehow...
But they are more on non catalogue ones of existing series like 3300uF KZE ones with only 10mm diametre...

A custom size of a standard series is easier to extrapolate specifications for.

If *everything* is custom then it makes replacement even harder.

Hm, the intereting thing is:
I've seen these caps in Seasonic, SirFa and Super Flower units so far...
And it seems FSP also uses them.

And only in 3300uF/16V in 10mm...

Hm...
