Key features

  • 1. Designed for Flat Cables up to 1.1 in Wide Includes dedicated flat cable ferrite cores that fit flat wires up to 1.1 inches wide—perfect for ribbon cables, flat power cords, and modern slim electronics where standard round cores won’t work.
  • 2. Complete Kit for Round & Flat Cables 20-piece set covers round cables (0.14–0.51 in / 3.5–13 mm) plus flat cables, giving you one versatile solution for all your devices.
  • 3. Effective EMI & RFI Noise Reduction Helps eliminate buzzing audio, signal interference, and screen noise by reducing electromagnetic and radio-frequency interference.
  • 4. Premium Ni-Zn Ferrite for Strong Performance Made from high-quality nickel-zinc ferrite to absorb high-frequency noise and improve signal stability for electronics and power systems.
  • 5. Easy Snap-On Installation – No Tools Needed Quick clip-on design lets you install in seconds—no cutting, unplugging, or tools required. Secure fit for both flat and round cables.

Most ferrite core kits are designed only for round cables—but many modern devices use flat cables that standard cores simply can’t fit. This upgraded 20-piece ferrite core kit includes specially designed flat cable cores that support cables up to 1.1 inches wide, making it ideal for ribbon cables, flat power cords, and low-profile wiring. Along with flat cable support, the kit also includes multiple sizes for round cables, covering everything from USB and HDMI to power and network cables. Built from premium nickel-zinc ferrite, these cores effectively absorb high-frequency EMI and RFI noise, helping improve signal clarity, reduce interference, and enhance overall device performance. With a simple snap-on design, installation takes just seconds—no tools or technical skills required. 👉 One kit handles both flat and round cables, giving you flexibility that standard ferrite kits don’t offer.

Free shipping included. 30-day hassle-free returns.
