61 ROD

Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
•– The last digit 1 = Uncoated Rod and 4 = Parylene Coated Rod. Parylene C is RoHS compliant.

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 67 material > 5.0 MHz.

The “Antenna/RFID Kit” (part number 0199000024) contains a selection of these rods.

•For any rod requirement not listed here, feel free to contact our customer service group for availability and pricing.

A high frequency NiZn ferrite developed for a range of inductive applications up to 25 MHz. This material is also used in EMI applications for suppression of noise frequencies above 200 MHz.

Strong magnetic fields or excessive mechanical stresses may result in irreversible changes in permeability and losses.

Available in 61 material:
EMI Suppression Beads
Beads On Leads
SM beads
Wound Beads
Multi-Aperture Cores
Round Cable Snap-Its
Toroids
