28 Snap-On Ferrite Cores Split Beads EMI RFI Filters Noise Suppressor Mixed Lot (also known as Ferrite Cores or Snap-On Ferrites) – used to reduce or eliminate Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) from electronic equipment.  You will receive various sizes: 6mm, 9mm, 10mm (0.40”), up to about 14mm Split Beads for most of your round Power, Coax, A/V, SVGA, and other cables.  I have recently become sold on the idea of using these Ferrite Cores on most of my computer and home theater equipment after reading a few articles and technical White Papers on the benefits of their use.  Most of us have experienced humming noises on our stereos or zig zag lines on our TVs due to interference from appliances like Microwave Ovens, Fans, CB Radios, etc.  After looking at a few of my computer peripheral and other cables, I noticed that there were these cylindrical bulbous objects at the ends of some of my better cables (USB, VGA, and DVI Cables to be exact).  Turns out, that these cables actually had Ferrite Beads built into them.  Unfortunately, not all cable manufacturers include these beads on their cables (I guess to save costs).  But you can easily add these Ferrites to your cables that don’t have them simply by clamping them over the cable.  Don’t worry if the bead doesn’t fit snugly over the cable – as long as it can close completely over the cable so that the Split Bead’s halves mate securely together, they will do their job.  A loose bead is better than one that doesn’t close over the cable entirely and leaves a gap.  You can keep the bead in place by using zip ties if you feel it necessary.  You can even loop the cable around the ferrite a few times to hold it in place.  The 411:   Easy to use – Just clamp them in place over the cable towards the end that enters or leaves your equipment  Helps to eliminate or suppress spurious RFI and EMI Noise  Great for use on Power, Coax, VGA, USB, Speaker, Telephone, and certain Vehicle Cables      Plastic housing encapsulates Ferrite Bead with snap clip for easy installation and removal
