A few years ago we had a need to shore up a 5 volt supply while power was collapsing to give a micro-processor time to finish its task so that it would be stable.  this was an ideal solution. (series diode feeding a 3 volt regulator for the uP)
For the final solution we went with a smaller value (0.25F from a physical size viewpoint so these are left over from the engineering prototype run. Approx 87 from an initial purchase of 100 are available
summary:
14.5 mm tall (0.57")
17.3 mm wide (0.68")
9 mm thick (0.35")
11.8 mm lead spacing (0.46")
Rated working temp is -40 C to +60 C . Derated to 3.9 volts @ 85 C
series resistance approx 0.5 Ohm. Negative lead is marked with a black band. as is typical with leaded caps, the longer lead is positive for easier insertion.
Ships with proper protection
