Review: Using these for RF suppression on USB cables. Worked well! - I am using these for ham radio transmitter applications. I use digital modes a lot, i.e. FT8. Occasionally I will have an issue where I key up the transmitter and the program goes nuts. Loses its connection to the radio and D to A / A to D converter (Signalink). I suspected the USB connection to the computer was being scrambled. I had bought the Signalink cables for between their TNC and the radio, which contain built-in toroids for RF suppression. But used a plain old USB2 cable I had lying around to save a few bucks. Well, apparently cheaping out burned me. I installed the RF chokes listed here, one on each end of the USB cable (choose an appropriate diameter), and the problems have stopped. I am impressed with the quantity and number of diameters that are include, and that the snaps to close the toroid are openable - so you can reuse these on other devices. Decent quality.
Review: Always something needing noise suppression. - One can never have too many ferrite ring cores. There's always some device that is suffering from RFI and these work well to limit it.

## Questions & Answers

**Q: what are the impedance @ frequency specs for these?**
A: I don’t know - it would be good if someone told what mix of ferrite these are made of.  Then all the specs could be looked up.

**Q: Do you attach one on each end of the cable near the plug? Or just use one per cable?**
A: I suggest you attach one on each one of the cable near the plug.

**Q: Has anyone figured out if these are type "Material 43" or is it something else?**
A: probably something else, based upon the price.

**Q: How could I use these on a radio antenna attached to my alarm clock? Place on the end of the antenna or at the base attached to the clock?**
A: If your antenna is a single wire, it'll choke off the signal entirely and ruin the antenna. If the antenna has a two-wire or coaxial connection at the clock, place one at the end where the antenna cable enters the clock. It'll choke off interference signals which are usually identical on both conductors (known as "common mode"), but will pass differential mode signals that go in one conductor and out the other, like legitimate signals an antenna would receive.

### ⭐⭐⭐⭐ I needed them due to a rare office location!
*by R***X on October 24, 2022*

My office is located next to a Dermatology office and I share a wall with them. We had moved in recently and I noticed that during certain times of the day my computer monitors and speakers would go crazy - feedback, weird patterns on one monitor, one monitor shutting off intermittently, speakers making loud hum with a repetitive pattern. At first, I thought my desktop was dying. Then I noticed it would only happen for about 45 minutes and everything would go back to normal. Then my coworker in another office - his wireless mouse would die with my computer would go on the fritz. I figured it had to me interference from a machine or equipment and did some research online regarding radiofrequency interference - causes, symptoms, and ways to cure. One day as my computer shut off a monitor and my speakers were making loud humming and clicking noises, I walked next door and asked if they had just started any particular equipment. Sure enough, they are running some skin treatment that uses lasers and radiofrequencies. They confirmed most sessions last about 30 to 45 minutes. Came here to Amazon, researched ferrite clipons - many different prices, sizes, suppliers, etc. This was the best mix of clips and price I found. Box arrived and I put on my speaker wires, monitors, just about everything. Now - NO HUMMING! No monitor shutting itself off. I do get slight patterns in my non- HDMI (just DVI) monitor hook up (I have 2 - one hdmi - one DVI) and that is how I know they are running the equipment. Then my coworker asked if I figured it out because his mouse stopped working and I put a clip on the wire to the IR sensor for his mouse and keyboard and it started working again. These clips definitely work and help. Not completely eliminated but now I can actually work and have speakers plugged in while the run the equipment. My situation is probably more unique but if you are having issues with radio interference these work. And I would say I probably have a high concentration of local frequency compared to most scenarios. (which is concerning for my own health...but I guess they don't make ferrite helmets!) The clips take a bit of massaging to get them to actually click and lock on. A slightly better design would resolved this but I did manage to get them all to stay on. This pack comes with various sizes to fit various wire sizes.
