• Prevention of high frequency interference entering
circuit electronics.
MULTILAYER SUPPRESSORS
Multilayer suppressors are a powerful solution for EMI/RFI
attenuation for electronic equipment. Supplied in four
standard sizes (0603, 0805, 1206 and 1806), they have
impedances between 30 and 1 000 Ω at 100 MHz.
Product construction
The use of silver for electrodes and terminations in
multilayer suppressors ensures high electrical
conductivity, which minimizes heat generation and
crosstalk.
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 0.6 A.
The internal construction can be single layer or multilayer,
depending on impedance requirements. Single layer
products have a meander design and are suitable for lower
impedances, while multilayer types have alternating layers
of ferrite and conductor stacked up to achieve higher
impedance levels.
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.
The terminal electrode forms a conductive connection to
the circuit. It is formed by three layers:
• Silver: for good conductivity
• Nickel: to protect silver termination against leaching
These characteristics can be used for many different
purposes:
• Tin-lead: applied to ensure good solderability.
• Absorption of generated noise.
The products are suitable for both reflow and wave
soldering.
• Filtering and wave-shape correction of digital signals
from high speed clock oscillators.
