I have a capacitor that says "104". What does that mean? ( IM finding a capacitor to use for that stamp serial connector)

    FYI you could have found the answer yourself just by typing 'capacitor marked 104' into Google

    104 = 10+4 zeros., I think

    superworms -

    Although I'm sure your answer was appreciated, it is subject to a bit of interpretation.

    Here is Mike Green's answer (above) which is a good deal more concise, and isn't subject to any interpretation:

    "1.0 x 10-4 farads or 0.1uf"

    The only reason why I point this out is that its's better to give newer folks answers which aren't subject to any interpretation, if possible, due to their lack of experience. I'm not "picking", honestly, just trying to be helpful, and enabling you to offer better technical advice.

    Regards,

    Bruce Bates

    im guessing that is in scientific notation? 1.0 x 10 to the 4th power?

    The point here is that the "code" on the capacitors is an expression of the capacitance in pico-farads (pF).·

    So, a 103 is a 10 with three following zeros: 10,000 pF ( = 0.01 uF).
    • 100 = 10 pF
    • 101 = 100 pF
    • 102 = 1000 pF····· (0.001 uF)
    • 103 = 10,000 pF··· (0.01 uF)
    • 104 = 100,000 pF·· (0.1 uF)·
    • 105 = 1,000,000 pF (1 uF)


    • 470 = 47 pF
    • 471 = 470 pF
    • 472 = 4700 pF····· (0.0047 uF)
    • 473 = 47,000 pF··· (0.047 uF)
    • 474 = 470,000 pF·· (0.47 uF)
    • 475 = 4,700,000 pF (4.7 uF)
