ClipOn Ferrite Core RFI Noise Suppressor — 1pc Key benefits Reduces electromagnetic interference (EMI/RFI) on power and data cables to help preserve audio, video and data signal quality. Simple snapon installation: clips onto the cable or power connector without cutting or locking the wire. Durable, heatresistant housing and nickel zinc ferrite core for reliable performance in demanding environments. What it does The magnetic ring structure absorbs frequency noise spikes that can cause audio hum, video artifacts or intermittent data errors, helping connected devices perform more reliably with minimal signal degradation. Compatibility and sizes Two size options to fit different cable diameters: Approx 17 mm cable: core dimensions 50 x 44 x 17 mm — fits cables up to 17 mm diameter. Approx 24 mm cable: core dimensions 43.5 x 41 x 24 mm — fits cables up to 24 mm diameter. Suitable for power cables, adapter leads and many data cables used with computers, monitors, routers and other consumer or office electronics. Materials and build Nickel zinc ferrite core for effective frequency suppression. Heatresistant shell protects the core and ensures stable operation under normal device temperatures. Snapon design requires no wire modification or specialized tools. Typical use scenarios Desktop workstation: clip onto the power cable of a PC or monitor to reduce perceived audio hum and video interference. Networking equipment: install on router or modem power leads to reduce EMIrelated packet loss or connection instability in congested environments. Home AV and set boxes: attach to power adapters to minimize interference that can affect sound systems or nearby sensitive electronics. Included 1 pc clipon ferrite core noise suppressor (select size according to cable diameter). Notes Choose the size that matches your cable diameter for a secure fit. Designed to help reduce frequency interference; results depend on the specific environment and devices in use.
