The magnetic ring can play a very good anti-interference effect, it can prevent the display signal from intruding into the equipment and other problems.
Suitable for all kinds of electronic equipment and wire/ power cord/platoon line/data line/signal line/USB line/AC line/DC line/audio line/ cable/ connection line/digital camera line and more.

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!

Used on both ends of a USB cable. Cured our noise issues.

Product was not what was said tried to make two different type of Baluns And they did not work. I don’t know what kind of material it was, but it did not work. I made a 49 to one with other Toroids That I knew that were correct and they worked fine. Try these two made them the same way they did not work.

Poor packaging ruined them not once but twice. The one of four that arrived in one piece looked nice but good luck receiving these un smashed.
