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 significantly affect 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 smaller, lighter 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 multiple amounts of peak impedance.
Example: Two wire turns provide 4 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 by 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.

High Frequency Ferrite EMI Cores
Split, Snap-On Ferrite Cores in Plastic Cases
300 MHz to 2 GHz Optimized
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.

Broadband EMI Ferrite Split/Snap-On Cores
In Plastic Cases
For Round Cables & Wiring Harnesses
For retrofit and post-assembly operations, Laird Technologies’ offers a selection of “split” cores. Similar in performance
to the one piece core designs, 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.

Broadband Split Ferrite Cores
For Ribbon & Flex Cables
Laird Techologies’ offers a selection of broadband “split” ribbon and flex cores for retrofit and postassembly 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.

Part #28S2001-2A2 split ferrite core assembly with hinged black plastic case
Split ferrite cores for flat / ribbon cables are sold as single sides. It is necessary to order
two sides to form one set. [Except 28S2001-2A2 (Figure 3) which is sold assembled]
Plastic Clip Assemblies: To specify one core side and one white plastic clip together, replace the second ferrite core part number character
after the dash with the letter “P” (example: 28S2022-0P0). One complete assembly of two ferrite core sides (28 material) with two plastic clips
would be specified as follows:
2 of part # 28S2022-0P0. Attachment ears are standard.
Metal Clip Assemblies: To specify one core side and one metal clip together, replace the second ferrite core part number character after the
dash with the letter “M” (example: 28S2022-0M0). One complete assembly of two ferrite cores (28 material) with two metal clips would be
specified as follows:
2 of part # 28S2022-0M0
Clips for Bulk Shipment: To order white plastic end clips (with attachment ears) separately in bulk, specify part number ASSE001-2. To order metal
end clips separately in bulk, specify part number ASSE017-2. No standard clips are available for 28S2827-210.

Ferrite EMI Disks and Plates
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).
Features:
• Easy installation • Each part for volume production is provided with permanent, double sided 3,5 mil acrylic adhesive
with 218 oz./inch2 adhesion. • Samples and sample kits are available with removable and reusable adhesive for "trial
and error" testing • Variety of sizes offered • For frequencies above 250 MHz, H series material is generally better than
M series material • Custom parts also available.
Applications:
• 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.

Example Application Graph Explanation:
The zero line on the graph represents the base line noise recorded for an
unprotected microprocessor. The curves (dB down) represent the performance
of the Laird Technologies’ ferrite plates 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. In the example
application graph above, the ferrite plate MP1040-100 exhibits up to a 1 dB
advantage over the HP1040-100 from 1-100 MHz, while the HP1040-100
exhibits a 0,5 dB advantage between 200 and 400 MHz. Performance can
vary with different sizes, materials, processors and applications.
