    Hello
    I have some small square green capacitors in my capacitor draw and have no idea how to read the value of them. I think they are called Mylar cap's. they have markings like this on them:
    > 2A152K
    > 2A472K
    > 2J332K

    If you know how to read them could you please explain this to me or send me a link were i can find out

    the "152" marking means 15 followed by 2 zeros = 1500. This will be the capacitance in pF, ie: 1500pF or 1.5nF

    Similarly the other values are 4.7nF and 3.3nF

    Ok thanks but do i use this method with all mylar Cap's

    So if it said 122

    = 1200pf, 1.2nf

    And do i have to worry about the 2J?
