Thin and Flexible Ferrite Core: FFPC Series

Thin Ferrite Sheet provides optimal EMC soution for FPC (Flexible Printed Circuit) and FFC (Flexible Flat Cables).

  • Noise filter with sintered body for FPC which has reduced thickness overcoming the rigid and brittle feature of ferrite core.
  • Higher insertion loss in the low-frequency band compared to EMI absorber sheets and achieves excellent performance in suppressing noise.
  • Available in a sheet form.
  • Prevents the effect of internal interference from radiation noise generated from FPC cable use for DSC, DVC, and laptop computers, and the immunity measures as well as terrestrial digital built-in apparatus etc.
