Possibly an Epcos B49410B2276Q000, now obsolete. It was 75mm diameter
by 150mm tall, rated at 2.5V (2.8V surge).
Epcos made supercaps up to 5kF, but they appear to have gotten out of
that market. Capacitors up to 100F are readily available from other
vendors; I haven't looked for alternate sources of larger values.
