Hello All, I have on the bench a couple of PSU's which have some failed Nichicon PL series caps. They didn't "puke" their guts through the top, but instead "diarrhea'ed" corrosive brown electrolyte through the bottom, down the legs and onto the board. On one cap, the electrolyte rotted the cap right off the board leaving 2 little stubs, and also corroded a trace on the foil side.

The PSU's are Power-One MAP series and are ringing-choke topology. The semiconductors have date codes in 1993. The PSU's were used in a commercial application, fan-cooled. They had failed...

I want to calculate capacitor ESR referring to below guide.

I must find out dissipation factor(Tan(δ)) for nichicon lxj series(6.3v 1500uf,25v 1000uf ,10v 2200uf)
I finally found out datasheet which has all series of nichicon capacitor.But unfortunately, It removed old nichicon capacitor.
Is there anyone who still has old nichicon datasheet which has information of LXJ series?

A few days ago,I destroyed one of my japanese retro game console by pluging it to 220v outlet.

and I finally fixed​ this retro game console by soldering varistor and glass fuse.

But I noticed that When I measure voltage of PSU's 5pin connector, it is 8.80-9.07v, 5.13v,3.40-3.48v,GND,GND instead of its rated voltage of 9v 5v 3v GND GND.
I have spare console...
