RFI Noise Ferrite Core ClipOn Filters Key benefits Reduces electromagnetic (EMI) and radiofrequency interference (RFI) to improve signal integrity without degrading the transmission. Preserves audio, video and image quality so sound and picture remain uninterrupted. Quick, secure installation with a snapon magnetic ring clamp — no complex tools or wiring changes required. What it does Single clipon ferrite core clamp that suppresses frequency noise on cables and leads. Filters unwanted interference while maintaining the original transmission characteristics of the cable. Features Ferrite core construction for effective EMI/RFI suppression. Clipon clamp design for easy application and removal. Snapon magnetic ring structure for fast, reliable closure and repeatable use. Available in multiple sizes to fit a range of cables, including 17 mm and 24 mm options for wide compatibility. Compatibility and use Designed to work on a variety of device cables and wires; suitable where noise suppression is needed without changing connectors or signal paths. Fits many common cable diameters thanks to the multiple size options (including 17 mm and 24 mm). Typical applications Home AV and entertainment systems: place on HDMI, speaker, or power leads to reduce hum, buzz, and video artifacts. Computers and peripherals: use on USB, power, and data cables to reduce interference that can affect audio playback, webcams, or data transfer. Cameras and surveillance: install on power and signal leads to minimize image or audio noise in CCTV and professional camera setups. Installation notes Open the clip, position it around the cable, and close the snapon magnetic ring until it locks. Repeatable and removable for testing or repositioning. Choose the size (for example 17 mm or 24 mm) that matches the cable diameter for performance. Materials and performance Ferrite core material provides broadband suppression of frequency interference while retaining signal quality. information Available in multiple sizes; please select the appropriate diameter (including 17 mm and 24 mm) to match your cable.
