This is not normally printed on the case of the cap. Typically larger (physically) caps will have a lower ESR (don't know what that stands for, but high ESR is real bad for a power supply cap). So just go for the same voltage, lower ESR (or physically larger package, or labeled "for power supplies". Charles Marslett chasm@killer.dallas.tx.us
