Note: the designation of brands ferrites

  • HV - high - frequency nickel-zinc (Ni-Zn) for weak magnetic fields;
  • GNP - high - frequency nickel-zinc (Ni-Zn) for the frequency;
  • NN - bass-nickel-zinc (Ni-Zn) for weak magnetic fields;
  • NM - bass-manganese-zinc (Mn-Zn) for weak magnetic fields;
  • the NMS - bass-manganese-zinc (Mn-Zn) to strong magnetic fields.
