Looks like 100uF, 16V. *Might* be Panasonic FP series, but the markings don't match what's shown in the data sheet Mouser currently links to. It may be an older cap and they've changed the markings, or it may be a different manufacturer/series. It does look like 100uF @16V, though, whoever made it...

The marking is typically digit-digit-multiplier. Think of the multiplier simply as the number of zeroes to put after the digits. In your case, 1-0-with one additional zero for 100uF. 471 would be 470uF (4-7-with one additional zero), 1000 would be 102 (1-0 and two more zeroes) and 100 would be 10 (1-0-with zero additional zeroes resulting in 10uF)

It gets a little weirder when they're values with a decimal; those are typically displayed with an 'R' where the decimal point would be, thus still giving a three digit code. For instance, 2.2 uF would be shown as 2R2, and 0.47uF as R47.

Hope this helps.
