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.

Features

• Monolithic structure for closed magnetic path and

highreliability

• Standard EIA and EIAJ sizes:

0402, 0603, 0805, 1206, 1210, 1806 and 1812

• High impedance per volume which leads to effective

high density circuits

• Suitable for wave and reflow soldering

• Plating material lead-free

• Wide range of impedance values

• Superior physical properties

• Available in standard EIA and EIAJ tape-and-reel

• Operating temperature -40°C to +125°C

• 100% sorting out on impedance

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.
