Flat Cable Ferrite Cores

In stock

Flat Cable Ferrite Cores have a special design that helps eliminate noise on flat cables. They work by blocking the low-frequency noise and absorbing the high-frequency noise that emit from signal lines or power cables. This makes them ideal for use in electromagnetic emissions suppression and for radio frequency interference.

Our range are available in various insert lengths and MHz Impedances. They come in various types that are suitable for Flat and Ribbon Cables.

  • Ferrite Material: A5 and K5B (RMS-303)
  • Casing Material: Nylon 6/6 RMS-244
  • Clip and Spring Material: Stainless Steel RMS-305
  • Colours: Black and Grey
