Re: MMC take2



If they have a + and a - terminal (ie polarised) then they are
electrolytic. This could even be indicated by something as insignifcant
as a blob of paint on one of the terminals, or by a whole row of
++++++'s down one side of the can.

They may be OK for pulse use, but for heavy rapid discharge they must be
protected from reverse voltage kickback by a diode string in series or
parallel. Great for high power flashgun/strobe work though.
