Do you mean 25 uF? A 25 Farad capacitor would be about the size of
a beer barrel

No, I wrote correctly. 25 FARADS.
But, this is SMALL in comparison. Elna offers 600F @ 2.5V. About 5 long x
1.5 diameter!
YES, 600 Farads. I kid you not. I did a double-take on this one. Really!

Hmmm ... I wonder what the

the super capacitor field.

I remember in my high school physics class (1955) the instructor (ex-

really changed!
The materials have changed
, and truly looks useful!

I've
I've never seen one before, but I am curious ...

No relationship with the vendor or manufacturer, YMMV,
etc.
... if someone out there has one, please tell what you
think. This would be *awfully* handy for portable
use.

Steve,
It looks like 'specsmanship' to me - I looked hard at the 5 amps continuous
rating and then looked at the high current duty cycle specified and
concluded that it will not support a continuous string of dots no matter how
you slice it. Duty cycle/sec is a unit of measure that I have never
10 matches
