DESIGN & SELECTION “RULES OF THUMB”
SELECT THE APPROPRIATE FERRITE MATERIAL
For the EMI frequency range to be attenuated, refer to cable core material impedance vs.frequency chart above.
FERRITE MATERIAL COMPOSITION AFFECTS CORE PERFORMANCE MOST
High-performance material is best. Cheap, low-performance materials require the use of larger, heavier cores.
SHAPE (DESIGN) AND MASS OF THE FERRITE CORE SIGNIFICANT
L
Y
A
FFECT IMPEDANCE
DON’T OVER SIZE
Use high-performance ferrite material and select the smallest core that will do the job. High-performance material
allows the use of smalle
r
,
l
ighter and lower cost cores.
SELECT A FERRITE CORE THAT FITS OVER THE CABLE’S OUTSIDE DIMENSIONS
Core should slide easily over the cable during installation.
WHEN POSSIBLE, INSTALL A CABLE CORE OVER WIRES IN A COMMON MODE CONFIGURATION
(Out and back lines inside the same ferrite cable core). A differential cable pair inside the same core will make the ferrite core a
common mode choke that is not susceptible to saturation from very high currents.
INSTALL THE FERRITE CORE NEAR THE NOISE SOURCE
ADDITIONAL TURNS THROUGH A CORE WILL PROVIDE MU
L
T
IPLE AMOUNTS OF PEAK IMPEDANCE
Example: Two wire turns provide four times the impedance of one turn (pass through) the ferrite core. Also, with each added turn,
the peak impedance shifts to a slightly lower frequency.
TWO-PIECE SPLIT CORES ARE AVAILABLE
One-piece cylindrical or flat ribbon ferrite core shapes are usually preferable, but split cores can be used in applications where
cores cannot slide over cable ends and connectors. Some split cores are available with snap-on plastic cases or metal clips.
SIDE-B
Y
–
SIDE IMPEDANCE TESTING OF FERRITE CORES IS THE BEST WAY TO COMPARE
PERFORMANCE OF DIFFERENT CORES
Ferrite core impedance measurement equipment and test methods are not standardized in the industry.
Every ferrite company has their own test methods. Catalog (web site) impedance data cannot be accurately compared.
Optimized, high-performance, low-cost custom part designs are available.

FERRITE EMI CABLE CORES
HIGH FREQUENCY FERRITE
SPLIT / SNAP-ON, CORES IN PLASTIC CASES
300 MHZ TO 2 GHZ OPTIMIZED
Split, Snap-on Ferrite Cores in Plastic Cases
For retrofit and post-assembly operations, a selection of high frequency EMI “split” cores are offered. Similar in performance
to one-piece cylindrical core designs, these split ferrite cores provide excellent common and differential mode high frequency
EMI suppression on round cable and wire assemblies. Black plastic snap-on cases provide secure closure of the split cores onto
the cable or wire bundle.

FERRITE EMI CABLE CORES
BROADBAND EMI FERRITE
SPLIT / SNAP-ON CORES IN PLASTIC CASES
FOR ROUND CABLES & WIRING HARNESSES
For retrofit and post-assembly operations, Laird offers a selection of “split” cores. Similar in performance to the one-piece core de
–
signs, these split ferrite cores provide excellent common and differential mode EMI suppression on round cable and wire assemblies.
Black or white plastic snap-on cases provide secure closure of the split cores onto the cable.

FERRITEꢀEMIꢀCABLEꢀCORES
BROADBAND SPLIT FERRITE CORES
FOR RIBBON & FLEX CABLES
Laird Techologies offers a selection of broadband “split” ribbon and flex cores for retrofit and post-assembly operations.
Similar in performance to one-piece core designs, these split ferrite cores provide excellent differential and common mode
EMI suppression on flat cable assemblies. Lightweight, inexpensive metal or plastic end clips and cases provide secure
closure of the ferrite onto the flat cable.

FERRITE EMI DISKS AND PLATES
PART NUMBER SYSTEM EXAMPLE
Ferrite disks and plates provide a simple, cost-effective
solution for radiated and inductively-coupled electromagnetic
interference. After the PC board soldering process, a ferrite
disk or plate can be installed directly on the source of EMI
(such as active devices or unwanted antennas).

• Ferrite disks and plates can be utilized either as inductively
coupled components or EMI shields on PC board components
and traces. Inductive coupling occurs when the ferrite affects
the conducted wave form leaving the active component.
The rise time of the wave form is effectively slowed by
the ferrite, and the overshoot and associated ringing are
attenuated. EMI shielding occurs when the ferrite absorbs
the radiated emissions from active components, effectively
protecting other boards or components in the vicinity from
radiated contamination • Can be used to locate unwanted
EMI antennas • Flat flex & ribbon cables • Can also provide
retrofit, auxiliary EMI attenuation

EXPLANATION:
The zero line on the graph represents the base line noise
recorded for an unprotected microprocesso
r
. The curve
(dB down) represent the performance of the Laird’s
ferrite plate relative to the baseline. The addition of the
ferrite plates to the top of the processor in this specific
application exhibits up to a 5 dB EMI reduction relative to
the unprotected part. Performance can vary with different
sizes, materials, processors and applications.
