Ferrite Filter — Model A110A Key benefits Reduces electromagnetic and radio-frequency interference (EMI/RFI) on cables to improve signal stability and decrease noise. Helps prevent data errors, audio/video hiss, and equipment interference without altering cable function. Simple clip-on design for fast installation and removal when testing or reconfiguring equipment. What it is and how it works Compact ferrite choke with a ferrite core encased in a durable plastic housing. The ferrite material absorbs high-frequency noise traveling along the cable, dissipating it as heat and lowering interference levels. Passive, maintenance-free component that requires no power or configuration. Main features and specifications Model: A110A Product name: Ferrite Filter Materials: Plastic housing, ferrite core Fit for cable diameter: 11 mm Size: 32 x 20 mm (1.3" x 0.8") (L x D) Color: Black Net weight: 277 g Compatibility and performance Designed to clamp onto cables up to 11 mm diameter. Suited for a wide range of signal and power cables where space and cable size match the specified dimensions. Effective for reducing high-frequency interference on digital and analog lines; performance depends on system frequencies and installation environment. Typical applications Home AV: Install on HDMI, audio, or power cables to reduce picture/audio artifacts and hum caused by interference. Office and IT: Use on USB, Ethernet, or power leads near monitors, routers, and workstations to improve signal reliability. Industrial and lab equipment: Fit on control, sensor, or power cables to reduce EMI in environments with motors, inverters, or switching power supplies. Installation notes Open the clip, place it around the cable at the point closest to the noise source or the equipment, and snap closed until it locks. For greater attenuation, multiple clips can be installed spaced along the cable, but verify cable diameter and space constraints. Packaging and handling Black plastic housing resists wear and allows discreet mounting. Keep away from strong mechanical shock during handling; ferrite cores are brittle and can break if dropped. Model A110A ferrite filter provides a straightforward, passive solution to reduce cable-borne interference while maintaining cable integrity and ease of use.
