I don't know if this is technical enough to be put in here, but anyway...

I dissected one of those shaking flashlights, and instead of using a capacitor to store charge, it uses this thing. I'm pretty sure that's not a capacitor since it doesn't even have any capacitance rating. Just "NT 473" whatever that means. Google doesn't find anything.

47x10^3uF apparently.

Usually caps using the digit-digit-mult system refer to the value in pF, but I guess they make exceptions for things that would go over a single digit multiplier (as some of the ones in this series do...)
