2001 jan 20 2 ferroxcube emi-suppression products 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 ? 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 0.6 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. product construction the use of silver for electrodes and terminations in multilayer suppressors ensures high electrical conductivity, which minimizes heat generation and crosstalk. 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. 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 ? tin-lead: applied to ensure good solderability. the products are suitable for both reflow and wave soldering. type number structure type numbers for these products consist of the following: fig.1 structure of electrodes. handbook, halfpage solder nickel silver metallization electrodes cbw355 fig.2 internal structure of multilayer suppressors.. handbook, halfpage single layer multilayer cbw360 multilayer suppressors
