Split Ferrite Cores for Flexible Circuits: GFPO Series (Patented)

Open magnetic circuit structure provides high impedance with close contact on FPC. Easy installation on flexible circuits in original design or retrofit applications for the suppression of radiated emissions up to 1 GHz and full compliance with the international EMC regulations for electronic equipment.

  • Nickel-Zinc ferrite cores with a new special design for better conformability and improved EMI suppression performance on flexible printed circuits.
  • 2-piece core for convenient fitting on pre-connected data lines virtually eliminates the gap between the ferrite and the flexible circuit, thus providing superior noise attenuation in a broad frequency range.
  • Parts can be optionally supplied with adhesive tape for convenient attachment to the flexible circuit.
