Ferrite Beads
Signal Line Multilayer Ferrite Chip Beads Z-SMS
Overview
KEMET Z-SMS Signal Line Multilayer Ferrite Chip Beads
are ideal for high frequency noise countermeasures for
digital product clock lines and general signal lines.
The small size of this ferrite bead makes it suitable for
mobile equipement that requires tight space both in
dimension and in height. The internal silver printed layer
structure creates a closed magnetic circuit which acts
as a magnetic shield to minimize heat generation and
crosstalk.
Using different type of materials enables to further
specialize the function and characteristics of the chip
bead:
1) Material “A” for broadband noise suppression. Low
R-XL frequency cross point and large resistance part
work as damping function, suppress unnecessary
resonance and keep signal integrity.
2) Material “B” for noise suppression above 20 MHz,
with increased attenuation. For general use especially
effective for video signal lines.
3) Material “C” for high frequency noise suppression
above 100 MHz. For high speed signal line, effective for
clock line.
4) Material “D” for noise suppression around 200 MHz,
effective for EMC regulations.
5) Material “E” for strongly suppressing unnecessary
resonance from low frequency range, due to lower R-XL
frequency cross point compared to material “A”.
6) Material “F” for noise countermeasures around LSI
power supplies. This is a low DC resistance version of
material “A”.
Applications
• PC, tablet, peripherals
• Interfaces, harness connectors
• Mobile and portable equipment

Handling Precautions
Ferritechipbeadsshouldbestoredinnormalworkingenvironments.Whilethesebeadsthemselvesarequiterobustin
otherenvironments,exposuretohightemperatures,highhumidity,corrosiveatmospheres,andlong-termstoragedegrades
solderability.
KEMETrecommendsthatmaximumstoragetemperaturenotexceed40°Candmaximumstoragehumiditynotexceed70%
relativehumidity.Atmospheresshouldbefreeofchlorine-bearingandsulfur-bearingcompounds.Temperatureuctuations
should be minimized to avoid condensation on the parts.
Foroptimizedsolderability,ferritechipbeadsstockshouldbeusedpromptly,preferablywithinsixmonthsofreceipt.”
