1. 43 Material Characteristics
This NiZn is our most popular ferrite for
suppression of conducted EMI from 20 MHz to
250 MHz. This material is also used for inductive
applications such as high frequency commonmode chokes.
EMI suppression beads, beads on leads, SM
beads, multi-aperture cores, round cable EMI
suppression cores, split round EMI suppression
cores, round cable snap-its, flat cable EMI
suppression cores, flat cable snap-its,
miscellaneous suppression cores, bobbins, and
toroids are all available in 43 material.

2. 61 Material Characteristics
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.
EMI suppression beads, beads on leads, SM
beads, wound beads, multi-aperture cores,
round cable EMI suppression cores, round cable
snap-its, rods, antenna/RFID rods, and toroids
are all available in 61 material.
Strong magnetic fields or excessive mechanical
stresses may result in irreversible changes in
permeability and losses.
