Tamicy 60 Pieces Clip-on Ferrite Ring Core RFI EMI Noise Suppressor Cable Clip for 3mm/ 5mm/ 7mm/ 9mm/ 13mm Diameter/Video Cable Power Cord (Black)

Used properly these will solve your problem with interference. You get a lot for your money with this assortment and these are actually surprisingly high quality.

These ferrite cores seem to work just fine as basic HF chokes, and I feel they are a good deal at this price. I ran a test on my NanoVNA with 5 windings into the core to see which frequency range these ferrites can suppress, and they seem to do a good job between 3.5 MHz and 56 MHz. I hope this basic test on the NanoVNA helps others decide if these will help their situation.

I’m extremely satisfied with the Tamicy 60 Pieces Clip-on Ferrite Ring Core Kit. This set is a fantastic value, especially for anyone dealing with RFI/EMI issues in a ham radio, audio, or general electronics setup. The variety of sizes (3mm, 5mm, 7mm, and 9mm) makes it easy to find the right fit for different cables, from small USB cords to thicker power lines. The clip-on design is super convenient—no need to disconnect or rewire anything, just snap them on and you’re good to go. I immediately noticed a reduction in interference and noise, particularly on my radio equipment and computer peripherals. The build quality feels solid, and the clips stay securely closed without slipping. Overall, this is a must-have kit for anyone looking to clean up signal noise efficiently and affordably. Highly recommended!

Seam to work well. Used on a truck with a little noise in the radio.

I was having static issue on my Jeep's radio after installing some lower-cost headlights. Evidently, it's a thing. Regardless, I popped a couple of these on each of the power leads to the headlights and it has helped some. It decreased the static noise on most stations, but not all. I may need to add a couple more. Regardless, these are super easy to install once you figure out which size you need to use. They fit around cables well and with a variety of sizes on this pack, I should be able to use them in a variety of applications. They feel weighty in the hand, so I imagine they should be durable enough to withstand normal wear-and-tear. I know the real solution to my problem is to get better headlights. That's the ultimate goal/solution but for now, these ferrite rings get 5/5 Stars from me. Let me know if any questions!

Works great got rid of rf noise

I used these to fix an electrical interference issue with a wireless 3-way switch that I had previously installed in my kitchen to control three recessed light fixtures. This is basically a surface mount rocker switch that sends a radio signal across the room to a receiver... like a garage door opener. The system worked fine with incandescent bulbs, but when I installed LED's in the three recessed light fixtures, the switch would only work intermittently. I put one of these ferrite on each of the two wires feeding each light socket (needed to reach up into the recessed light to install, which was a bit tricky due to space constraints). So this was two beads per light. After installation, the wireless 3-way switch is working correctly again. No issues since installation. Very pleased to be able to upgrade the lighting to LED and keep the switch functionality. Worked very well, as described. I gave 4 stars for installation because the hinges on the plastic over-mold were pretty flimsy and it took some finesse to get the two halves to line up so that the clasps would latch. Keep in mind I was working overhead and blind with my hand inside a recessed light. If you snap these onto a wire in a normal setting, there is NO issue. Very pleased and would purchase again.

I wonder if?? Right!? Well I'm here to tell you yes these things really do work! I did my research and purchased the Tamicy brand 60 pieces assortment pack. But the bottom line is they do suppress unwanted noise and interference. I got them for my CB stuff and got them on all most everything. I'm talking- my CB -the coax the power amp and the power meter. I did that on my flat s reen tv -cable coax- wall a/c plug- plug in lites -if it has a cord it's got one on it..they are easy to use and good quality and good price.

Poco que compartir son cables de muy buena calidad - es todo.-.-.-

Have used nearly all of these they are used to reduce the effect of radio frequency interference. Have not carried out definite testing to determine if within specifications. However they have worked in all all instances where required.

used on the AC power lines to LED lights

Satisfactory for reducing domestic stray RFI...adequate light usage. Sometimes an electical tape wrapping needed to keep a loose ferrite clip tight. Thank you.
