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.
