Ferrite Beads
Power Line Multilayer Ferrite Chip Beads Z-PMS
Overview
Applications
KEMET Z-PMS Power Line Multilayer Ferrite Chip Beads
are ideal for high frequency noise countermeasures on
the DC power supply line.
• PC, tablet, peripherals
• Differential transmission line on USB and
IEEE1394 interface
• Mobile and portable equipment
The small size of this ferrite bead makes it suitable for
mobile equipement that requires tight space both in
dimension and in height. The unique green sheet and
printing technologies realize low RDC which leads to
lower power consumption and longer battery life.
Using three 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 efficient
for video signal lines.
Benefits
• Miniature and low profile
• Reduced power dissipation due to low RDC values
• No grounding needed for flexible circuit design
• Prevents interference between circuits in mobile
systems
• Impedance value from 10 – 390 Ω
• Rated current range from 0.8 – 4 A
• Operating temperature range from –55°C to +85°C

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 fluctuations
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.”
