Soft Ferrite: Extruded

The only option for medium to high-volume quantities when length exceeds 2″. Custom lengths available with maximum standard lengths of ~7.5 to 8″. Diameters available from ~0.125 to 1″, tight tolerances available with centerless grinding. Most sizes available and custom tooling is inexpensive. Refer to Effective Permeability of Rods for relationship between material permeability and length-to-diameter ratio. Refer to material tables for available Materials and Notes below for further ordering information. Typically used as antennas (transmit/receive & RFID), transformers or impeders for high-frequency welding.

Notes:

  1. Material (-XX): prefix for NiZn (ie.RMX-) or suffix for MnZn (ie. –M20).
  2. Length: (-XXXX-): made to order, insert dimension (ie. RX-500-2500-M20)
  3. Tolerances (dimensional – cross section): ±5%
  4. Tolerances (dimensional – length): ±2%
  5. Tolerances (dimensional – straightness): 0.011/inch (0.050 max)
  6. Tolerances (inductance & Q): ±10% & -20% (grading available)
  7. Grinding: available for tighter tolerances
  8. Slots (impeders): for water cooling (as is ID for tubes), dimensions reference
