I have been looking at several designs for propeller clocks. All the ones I have seen that incorporate super caps use a a value of 47,000 ufd.
I fully understand that the purpose of the super cap is to supply power to the PIC while it is spinning or in the case of a clock that uses a generator to generate the PIC power, power it while it is not spinning.
I would like to know why 47,000 ufd? Why not 45,000 or 50, 000?
And is the fact that a cap is 47,000 ufd make it a super cap? Or is there something special about supercaps?
