Hi All. Im currently working on a repair attempt of my active loudspeaker.
After examination, 1 of the two inductors on the PCB is spoilt.
The only thing written on the inductor is 22uH. How can I get replacement for this? I mean a typical inductor rating would be something like :
22 μH ±10% Ferrite Leaded Inductor, 2.8A Idc, 40mΩ

I've attached pictures of the inductor
Does the %, type, A and mΩ matters?

 

The tolerance is probably least important, but the inductor needs to be able to handle the speaker power so the current rating and resistance will be important. If you do not know these values for the original inductor then you will probably be close enough if you find one with similar construction and size to the original.

Thanks. I'd thought so too. Does the dot on top of it means anything? I saw there are from none to 1 and 2 dots

 

If they have a meaning then I don't know what that might be.
