They just fit edge to edge (fatter but not extremely tall), lead for lead and come within a hair of the roof cover. 105c, extremely low ESR mil-spec. New old stock Navy shipboard stuff. Beatza snot outta original 680uf 200 volt 85c capacitors.

Going to place an order this week. They have been stored in Henderson Nevada so they enjoyed bone dry air. Owner says they have been "sealed" in preservative bags at his place since 1998.

I am going to purchase (20) Even my Meanwells use the same caps at the Megawatts.

Hopefully the electrolyte hasn't dried up, big problem for surplus caps.

Gordon Three OOPS!

" Hopefully the electrolyte hasn't dried up, big problem for surplus caps"

I was hoping the sealed bags would help stop that. Would my ESR tester reveal an "over stored" electrolytic?


Nyet on Allectronics having them. Not even Newark or Digi-Key have them.

That voltage rating is what attracted me. Twice that of OEM design.

Yes, testing should show out of spec if there's an electrolyte problem.
