Part Type Information
These rods are designed for use in antenna and RFID transponder applications. Rods are available
in three materials to cover a frequency range from 50 kHz to 25 MHz. Suggested frequency
ranges: 78 material < 200 kHz, 61 material 0.2 -5.0 MHz and 61 material > 5.0 MHz.
-See www.fair-rite.com/newfair/catalog_rodinfo.htm graphs for temperature information for these
rods.
-Rods can be supplied with a Parylene C coating. Parylene coated rods have a '4' as the last digit.
Parylene C is RoHS compliant.
-For any rod requirement not listed here, feel free to contact our customer service group for
availability and pricing.
-The Antenna/RFID Kit (part number 0199000024) contains a selection of these rods.
-Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade, the last
digit 1 = uncoated rod and 4 = Parylene coated rod.

Preferred parts, the suggested choice for new designs,have shorter lead times and are more readily available.
The column H(Oe) gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. The actual dc H field in
the application is this value of H times the actual NI (ampere-turn) product. For the effect of the dc bias on the impedance of the bead material,
see figures 18-23 in the application note How to choose Ferrite Components for EMI Suppression.
A ½ turn is defined as a single pass through a hole.
