MULTILAYER SUPPRESSORS
Multilayer suppressors are a powerful solution for EMI/RFI
attenuation for electronic equipment. Supplied in seven
standard sizes (0402, 0603, 0805, 1206, 1210, 1806 and
1812), they have impedances between 6 and 2 000
Ω
at
100 MHz.
When installed in series with signal and/or power circuits,
high frequency noise is suppressed. There is no need for
ground termination, which makes these devices very
suitable for circuits with difficult ground. Typical
suppression frequencies range from 10 MHz to 1 000 MHz
and rated currents are between 0.1 and 6 A.
Multilayer suppressors are specially designed to reduce
noise in low impedance circuits while keeping the signal
free from distortion. This is because at the interfering
frequencies these components behave as a resistor. The
high frequency noise is converted into heat rather than
reflected to the source. This dissipation prevents ringing
and parasitic oscillations.
These characteristics can be used for many different
purposes:
•
Absorption of generated noise.
•
Filtering and wave-shape correction of digital signals
from high speed clock oscillators.
•
Prevention of high frequency interference entering
circuit electronics.
Multilayer suppressors
Main applications areas for multilayer suppressors
are:
•
computer and peripheral equipment: mother board,
notebook, CD-Rom, DVD-Rom, CD-RW, scanner, hard
disc, VGA card, sound card, LCD monitor, printer, PC
server thumb drive, PCMCIA card, graphic card, etc.
•
network: LAN card, hub, switcher, router set top box,
etc.
•
telecom: cell phone, ADSL, wired modem, cable
modem, ISDN, GPS satellite receiver, etc.
•
consumer: walkman, walkdisc, digital still camera
(DSC), sound system, HDTV, projector, DVD player,
VCD player, tuner for TV, cable modem, etc.
To help designers in the trial and error process of finding
the most suitable suppression component, we offer a
sample box with a selection of products.
