Ferrite EMI Disks and Plates
Features:
• Easy installation • Each part for volume production is provided with permanent, double sided 3,5 mil acrylic adhesive
with 218 oz./inch
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 com-
ponents 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.
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).

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.
