Using super cap for smoothing

[shumifan50]

I have some 47000uF supercaps and I wonder of I can use them to smooth the output of a rectifier (5V after rectification) in a PSU. They are 5.5V supercaps.

If they are standard super caps then probably not, the ESR is quite high on the standard types. Do you have a data sheet for them you can post here.
Thanks
Adam

Hi Adam, Thanks for your response. Unfortunately I have had these for a while and cannot remember where I bought them (seemed like a good idea at the time for model trains to help with bad contacts on the track, but voltage was wrong). There are no identifying markings on them, just the values.

Ok can you take a pic? I might be able to recognise the type from a pic.
Cheers
