    Hello everyone, I have been lurking for a while and now I need to ask a question (or ten).

    Electronics was a hobby for me about 30 yrs ago, I have missed it and I am getting started again. I have started accumulating various parts again, very different from scrounging old TV chassis' back in High School (no e-bay then:D).

    The reason for my post is I have aquired a mixed assortment of ceramic and mylar(?) caps and I have been trying to decode (don't remember ever seeing this system before) and sort them. :confused:

    I did find a good explaination and a program that helps with this but I have run into problems with some of them as they do not seem to fit the standard format.

    Format example:
    KCK
    100Z
    50V

    All values are read in picofarads so this would be 10 pF -20%, +80% tolerence. Not sure what the KCK is for.

    The ones I'm have questions with are marked as such;

    Front......Back
    RMC .......20 (20pF ?)
    N750 ......5%

    Z5F
    .01+/-10% (.01pF ?)
    100v

    NPO
    12+/-5% (12pF ?)
    100V

    20J (20pF, +/-5% ?)
    N750
    100V

    RMC
    47N150 (47pF ?, whats the 150 ?)
    10%

    <>
    .55P (.55pF, there is no P tolerence)
    3V

    Y5T
    .053 (.053pF ?)
    16V

    .0047K (.0047pF, +/- 10% ?) (mylar)
    100V-P

    Am I warm?

    Thank you!

    Well, welcome back ;)

    When I was a young teen, I asked my Dad if I could have the radio in his workshop, and he said OK. He didn't realize that I was going to completely dismantle it for parts. :eek:

    You should find all of the information you're currently looking for via links from those pages. It'll take some poking around, but it's there.

    Half the battle is just knowing where in the heck to look stuff up!

    Yea, got my butt smacked a few few times for similar things.

    as for poking around... I do that a lot. Great way to learn.

    Thanks for the link!
