Ferrite Magnetic Core Clip 7mm – Cable Noise Suppressor, EMI - RFI Filter

Reduce unwanted electromagnetic interference (EMI) and radio-frequency interference (RFI) on your cables with this clip-on ferrite core. Ideal for computers, TVs, modems, speakers, lab instruments, 3D printers, CNC controllers, and microcontroller projects like Arduino and Raspberry Pi, it improves signal integrity on USB, HDMI, DC power, and audio lines. Designed for quick installation, it delivers a cleaner signal path for clearer sound, sharper video, and more reliable data transfer.

✨ Why use a ferrite clip?

This split-core ferrite acts as a high-frequency common‑mode choke, attenuating noise on both power and signal conductors. By suppressing RF energy on cable shields and conductors, it helps reduce emissions and susceptibility—protecting sensitive electronics components and modules while stabilizing data links and supply voltage rails.

✅ Key Features

• Clip-on design for tool-free installation — no soldering required.
• Effective EMI/RFI attenuation on high-frequency noise for data and power cables.
• Reusable and easy to reposition — great for prototyping and troubleshooting.
• Works with USB, HDMI, DC power, audio, and other signal cables (within size limits).
• Perfect for Arduino, Raspberry Pi, ESP32, sensors, stepper drivers, and other microcontroller projects.
• Helps improve signal integrity and reduce both radiated and conducted interference.
• Supports cables with outer diameter up to 7 mm.

📡 Typical Applications

• Suppress noise from switching power supplies, motor drivers, and microcontroller clocks.
• Stabilize USB/HDMI links and reduce RF-induced artifacts in audio paths.
• Mitigate interference impacting Wi‑Fi, Bluetooth, SDR, and AM/FM reception.
• Quiet DC supply voltage lines feeding electronics modules and sensors.

🛠️ Installation Tips

• Clip onto the cable near the noise source or device end; for stubborn issues, use one at each end.
• If cable size and clip geometry permit, additional turns through the core increase impedance.
• Multiple clips can be used on the same cable for higher attenuation.

📐 Specifications
