Review on ๐Ÿ”’ High-performance Stardrift 10-Pack 3mm Ferrite Core Bead Choke Ring Noise Suppressor Filter for HDMI DVI VGA Cable - Black (3MM) by Vincent Burton

Check measurements before ordering.

A little background: I'm a radio amateur, often running 35-100 watts from my office. This sends enough interfering radio frequencies into adjacent computer cables that without the ferrite beads on either end of the links, the Caps Lock LED will light up and shut down or interfere with various peripherals during transmission. (My 27-inch aluminum iMac is inherently very well insulated.) I ordered these ferrite rings because they were advertised for USB cables. I had to think more about their 3mm diameter. They are great for mini and micro USB. Cables I have a few but unfortunately too small for my old plain USB cables. Time to pull out the calipers, measure something and order bigger chokes. as opposed to the type intended for permanent installation. Tiny pins hold the beads securely to the cords where they are installed and the beads close securely. The latches can be opened with a fingernail or a jeweler's screwdriver, and if you're careful they should provide a long reuse life on a variety of cables. Ferrite beads are cheap, however, and you should probably just leave them in place.
