RFI Noise Ferrite Core Clamp Filter (single clip-on) Key benefits Reduces electromagnetic (EMI) and radio frequency interference (RFI) to protect signal integrity without degrading audio, video, or data transmission. Prevents unwanted noise and glitches so you get uninterrupted audio, video, and photo capture or playback. Simple, fast installation saves time and eliminates the need for tools or cable re-routing. Features and specifications Single clip-on clamp filter: easy to apply to existing cables without disconnecting equipment. Snap-on magnetic ring design: secures quickly and removes concern about wire locking while keeping the clamp firmly closed. Two sizes available (including 17 mm and 24 mm) to fit a range of cable diameters and device cabling. Wear-resistant shell: durable under repeated use and stable in higher temperature environments. Maintains transmission signal quality while suppressing RFI/EMI. Compatibility and performance Designed for broad compatibility with many wire types and device cables; choose the size that matches your cable diameter (17 mm or 24 mm). Works passively—no power required—and does not alter the cable’s electrical characteristics when installed properly. Effective for reducing common-mode noise and high-frequency interference that can affect audio, video, and data lines. Typical use scenarios Audio and video production: attach to microphone, camera or monitor cables to reduce buzz, hum, and dropouts during recording or live streaming. Surveillance and CCTV systems: install on camera and power cables to improve image stability and reduce interference from nearby electronics. Computers and peripherals: clamp onto USB, HDMI, power, or data cables to minimize interference that causes data errors or degraded display/audio performance. What to consider when choosing a size Measure the cable bundle diameter and select the 17 mm or 24 mm clamp to ensure a snug fit. Proper sizing improves suppression effectiveness and keeps the clamp secure. What’s included One single clip-on ferrite core clamp filter with snap-on magnetic ring and wear-resistant shell (select size at purchase). Practical notes Install by opening the clamp, placing it around the cable, and closing until it snaps into place. No tools required. For best results, place the clamp near the noise source or at the cable entry point to the device. Multiple clamps can be used for heavier interference.
