Large shapes (typically squares/rectangles or discs) used for RF and ADF antennas for portable receivers and/or transmitters, EMI/RFI suppression or as substrates.  For Discs diameter typically ≥ 1″.

  1. Material (-X): prefix for NiZn (ie. M-1049) or suffix for MnZn (ie. B-1049-M20)
  2. Thickness: made to order (thinner available, maximum listed)
  3. Tolerances (dimensional): ±2% (nominal value may vary based on material choice)
  4. Grinding: available for tighter tolerances
  5. Tooling: call if require different size, for other Plate/Disc configurations also see SLUG or FERRITE MACHINED (CUSTOM CORES)
