line noise reduction.
The ferrite mix is not specified but since it is an iron mix we presume it to be similar to the 31 mix which is best for damping on-line noise. It seems to work very well for that. Properly wound, it makes a great common mode choke

These work and are a great price
Needed a couple of ferrite toroids between my solar inverter and my batteries to keep HF out of the batteries. They aren't the snap around type, but work great. These work. You won't find anything cheaper or large enough to allow two 2/0 wires through.

Works well for RF choke.
Works as advertised for RF.

Did it's job
Used on both ends of a USB cable. Cured our noise issues.

What happened… mostly good (75%)
I have (4) of these but this time one of the toriods had significant issues with magnetic permeability, ie low induction. With (2) turn of wire, all other toroid exhibit between 28 and 31 μH. The defective one had almost half at 18μH, see photos

Toroids most efficient.
Need for experiments.

Possibly some useful info.
Though I am very experienced in electronics, I am not super knowledgeable when it comes to Toroidal Inductors.Like I understand there many uses and all but as for calculations involving sizing, magnetics, saturation points and such...I just don't get it. I simply bought these for some in line noise suppression on a high power system that presumably has issue's due to a rapidly switching Solid State, Pulse Width Modulator. (Switching frequency likely under 1000hz.)I will see how it goes later.My lack of knowledge aside I took some measurements that may be useful for people.The inside of the ring was approximently 35.6mm or 1.4in. Outside was 61.15mm or 2.4in. Thickness was approximently 12.6mm or 4.96in.So overall the measurements were extremely close to the claimed amounts. However I designed up and 3d printed two sets of enclosures for these as additional protection from high voltage (240v) where they are going to be used.I noticed that even though one fit perfectly into the case I made. The other was too large by a hair.Turns out there is up to a 1mm difference in the size of these Toroids that I found in my sample. (+/- 0.5mm.)So be careful about that if you plan to make something like I did.Otherwise the magnetism seems quite strong for these for lack of better way to measure it.And the resistance I found across the two sides was about 5 to 7 kohm.Hopefully this is all helpful!
