Capacitor Value?

    I have some ceramic disc capacitors with 104 Z on them (the 104 is
    underlined), and they are about 7/16" diameter. Can someone please tell me
    the value so I can buy replacements?

    Thank you,

    104 = 1 0 0000 (4 zeros) or 100,000pF
    Value in nF= 100,000 / 1,000 = 100nF
    Value in uF = 100,000 / 1,000,000 = 0.1uF

    Z would be tolerance but my table doesn't cover that letter only up to K
    (+/-10%)

    Not sure about the 'z' (maybe tolerance) but the 104 is read like
    resistors; first 2 digits read as is and the 3rd is the multiplier; hence
    100000pF or .1uF

    Tolerance is given by letter codes:
    F = +/- 1%
    G = 2%
    H = 3%
    J = 5%
    K = 10%
    M = 20%
    Z = +80, -20%

    A*s*i*m*o*v

    .... Wasted power is current squared times the resistance.

    As ph12 stated so eloquently:
    Thank you for the information.

    As Wes. stated so eloquently:
    Thanks Wes. I had a chart quite a few years ago but has since been lost.
