    Determine the power of the ferrite ring in its dimensions

    Hello friends

    Is there a way to detect the ferrite ring power without the datasheet?

    I have a green ring ferrite

    inner diameter = 37mm
    External diameter = 63mm
    Height = 25mm

    Thanks a lot

    put 5 turns on it and measure the L, from that you can work out the Ur, if it is quite high ( > 3000 ) it is likely a common mode choke material - not a power ferrite.
