According to Ignoramus6399 :

Well, here's a picture of the data plate, courteously emailed to me by
the seller:

Maxwell Labs caps are really nice quality pulse discharge
capacitors.

Do you thikn that it has PCBs?

Hmm ... It says "impregnant MIPB" which sounds like something
different from PCBs. You might check whether they are still in
business, and ask them.

And these *might* actually surivive a dead-short discharge --
but it is still kinder to them to not do that.

Enjoy,
DoN.
