    Easy question....

    What is the overall tolerance of capacitors in serial and parralel ?

    for instance, if I have two 10% caps in serial what is the total
    tolerance? is it still 10% or 20% or 5% or what..???
    Is there a formula for this kind of stuff?
    Thanks

    i think you mean series.
    in any case, if both are 10% then the
    total string should be 10%.
    you can look at it this way.
    lets assume 2 100 Ohms are 10% and they are at
    their upper limits, which would be 110 ohm each.
    put them in series, you would have 220 Ohms
    instead of 200 Ohms.
    now what is 10% of 200 Ohms?
    220 8)
    so i guess the tolerance is still 10%

    sorry, i didn't see that you were referring to CAPs. the
    answer is still the same.
