    I need your assistance reading the codes on a stock polyester film capacitor. (Mylar)
    The code is as follows: 2A473K. I know the K stands for +- 10 % tolerance. I know the 473 stands for 47, 000 picofarads. What in the hell does the 2A stand for??? I can't find this information anywhere! :eek: My email address is [email protected].

    Capacitor detail

    Hi there. I am not sure, but you no the capacitance, and the tolerance, iam geussing you know the working voltage, there very stable caps as i know it, could the other data just be manufacturing data, not sure, but the detail you do know should allow you to use them. Dave.

    If the cap has a company logo on it, check their website.
    davelectronic's guess is probably correct.
    A lot of manufacturers use a prefix to designate a particular class or physical size of
    their specific product.
