Unique-Bargains 3.5mm Wire Cap Connector 20pcs Assorted Sizes

Assorted Ferrite Cores for Cable Noise Reduction

This pack supplies 20 clip-on ferrite rings in five different internal diameters ranging from 3.5mm to 13mm. Each size includes four pieces so you can match the core to the exact cable thickness you are shielding. The ferrite material suppresses high-frequency EMI and RFI generated by nearby appliances and electronics. They are intended for anyone who needs cleaner signals on power, USB, audio, video or data cables.

Clip-On Installation Fits Existing Cable Runs

The hinged plastic cases snap around cables without cutting or soldering, so they install on finished assemblies in seconds. Dimensions for each size are 13 x 25mm for 3.5mm and 5mm cores, 16 x 30mm for 7mm, 19 x 35mm for 9mm and 23 x 36mm for 13mm, covering cable diameters from 1.5mm up to 13mm. Because they are removable and reusable, you can reposition them during troubleshooting or move them to another lead. No external power or grounding connection is required.

Replaces Loose Beads or Tape-On Solutions

Builders who have been winding cables through loose toroids or taping split beads in place will find these clip-on cores faster to fit and more secure over time. The jump is worth it when you need to suppress interference on multiple cable types without permanent modification. They are not for installers who require adhesive-mount cores, screw-terminal filters or shielded conduit systems.
