Your cart is empty. Description:
-Clip on ferrite bead cable can be used on all kinds of wire cords such as: Power Cord, Audio Cables, Data Cable, USB Cables.
-It helps improving the electromagnetic field and signal quality around the cable, avoiding outside interference.
-It won't cause distortion of the transmitted signal and won't affect your audio, video and picture quality.
Note:
Please install them in place near the interference source. (Near the import and export of shielding case as much as possible.) If a cable has equipment that needs to be protected on both sides, install one at each end.

Took a bit of fiddling to discover how to open the clamping mechanism. Small jewelers screwdriver was the correct tool to get under the clip that secures the ferrite clamp. Did not appear to reduce the common mode noise I have been trying to discover the source and eliminate.

Well cant use any of the ones i received. Why? Because no one in my family of 5 can figure out how to open them up. No instructions came with.

Well designed to go around most cables, however, one out of the five delivered the latch is broken, so it will not close.

These work well at reducing Radio Frequency Interference. Snap Choke Cores will NOT eliminate RFI, but will reduce it to a point where interference will not be an issue. Take Note: the diameter of cable / power cord to be used on. The power cord on my microwave oven has a width of 12.7 mm (1/2 inch). The inner diameter of the snap choke core must have space to fit over cable / cord. The more snap choke cores used the higher the RFI suppression. So many uses: AC power cords, coax, DC power cables, Audio and Video cables.

Fit was just a little loose

It worked as it should. But I had a hard time opening the beads. Actually, I broke the first one. I should buy the other product with two clips. It is a good price and worked fine.

The center hole of the actual ferrite is 15 mm and is prefect. The center hole of the plastic cover which holds the ferrite in place is smaller than 15 mm and needs to be enlarged to fit over LMR 600. Once the hole is enlarged, they work fine. I would recommend them but be prepared to enlarge the center hole of the plastic cover.

I was always skeptical that these cores work but I saw them working in real time. I was helping a friend solve RF interference into his computer. His ham transmitter and antenna were very close to the computer and when he would transmit the screen would get a bunch of pattern lines on it, the keyboard and mouse would not work, and lots of noise coming out of the speakers. We started adding these cores to the power and signal lines for all the devices and one by one as we went the problem completely disappeared. Not just a little better or that's good enough. It was completely solved. I am no longer skeptical. I use these as well and I was able to get instant results solving some RF interference problems with a computer to ham radio interface. Make as many loops through the cores as you can and still snap it closed for best results. Buy with confidence. These work.

Inexpensive but very effective federate thank you on RFI free now.

I installed aftermarket LED headlights in my Cobalt SS. I normally use satellite radio so did not realize how much RF interference they produce until I used FM. These cores fixed this issue. Installed in about 2 minutes per side., ran double loop of input wire through core and no more interference.
