That seems too long for a capacitor code. . . It should only be 3 digits with or without a letter to indicate the tolerance. 470= 47 pico Farads 140= 14 pico Farads. I'd say it's more likely to be 47 pF.
the first 2 digits are the value, and the third is the miltiplier. ie 470 47 is the value, and multiply by 10 to the power of 0 (0 being the third digit) this gives the value in pico Farads.
If you want a capacitor code calculator, you can download 'electronics assistant' from www.electronics2000.co.uk
It does other calculations for you too (resistance, power, ohm's law etc)

As Nigel said, this is definitely an electrolytic capacitor (you can tell by the + symbol on the top, this indicates the positive lead.) And looking at the markings on the top, it's a 470:mu:F 40V. If it's one you're going to replace, replace it with equal or higher voltage rating. . .
