FERRITE MTERIL OMPOSITION FFETS ORE PERFORMNE MOST High-performance material is best. heap, low-performance materials require the use of larger, heavier cores. SHPE (DESIGN) ND MSS OF THE FERRITE ORE SIGNIFINTLY FFET IMPEDNE DON T OVER SIZE Use high-performance ferrite material and select the smallest core that will do the job. High-performance material allows the use of smaller, lighter and lower cost cores. SELET FERRITE ORE THT FITS OVER THE LE S OUTSIDE DIMENSIONS ore should slide easily over the cable during installation. WHEN POSSILE, INSTLL LE ORE OVER WIRES IN OMMON MODE ONFIGURTION (Out and back lines inside the same ferrite cable core). differential cable pair inside the same core will make the ferrite core a common mode choke that is not susceptible to saturation from very high currents. INSTLL THE FERRITE ORE NER THE NOISE SOURE DDITIONL TURNS THROUGH ORE WILL PROVIDE MULTIPLE MOUNTS OF PEK IMPEDNE Example: Two wire turns provide four times the impedance of one turn (pass through) the ferrite core. lso, with each added turn, the peak impedance shifts to a slightly lower frequency. TWO-PIEE SPLIT ORES RE VILLE One-piece cylindrical or flat ribbon ferrite core shapes are usually preferable, but split cores can be used in applications where cores cannot slide over cable ends and connectors. Some split cores are available with snap-on plastic cases or metal clips. SIDE-Y-SIDE IMPEDNE TESTING OF FERRITE ORES IS THE EST WY TO OMPRE PERFORMNE OF DIFFERENT ORES Ferrite core impedance measurement equipment and test methods are not standardized in the industry. Every ferrite company has their own test methods. atalog (web site) impedance data cannot be accurately compared. Optimized, high-performance, low-cost custom part designs are available.

21 RODND FERRITE EMI ORES FOR RION & FLEX LES Laird Techologies offers a selection of broadband split ribbon and flex cores for retrofit and post-assembly operations. Similar in performance to one-piece core designs, these split ferrite cores provide excellent differential and common mode EMI suppression on flat cable assemblies. Lightweight, inexpensive metal or plastic end clips and cases provide secure closure of the ferrite onto the flat cable.

27 FERRITE EMI DISKS ND PLTES Ferrite disks and plates provide a simple, cost-effective solution for radiated and inductively-coupled electromagnetic interference. fter the P board soldering process, a ferrite disk or plate can be installed directly on the source of EMI (such as active devices or unwanted antennas). FETURES: Easy installation Each part for volume production is provided with permanent, double sided 3,5 mil acrylic adhesive with 218 oz. / inch2 adhesion. Samples and sample kits are available with removable and reusable adhesive for trial and error testing Variety of sizes offered ustom parts also available. PPLITIONS: Ferrite disks and plates can be utilized either as inductively coupled components or EMI shields on P board components and traces. Inductive coupling occurs when the ferrite affects the conducted wave form leaving the active component. The rise time of the wave form is effectively slowed by the ferrite, and the overshoot and associated ringing are attenuated. EMI shielding occurs when the ferrite absorbs the radiated emissions from active components, effectively protecting other boards or components in the vicinity from radiated contamination. an be used to locate unwanted EMI antennas. Flat flex & ribbon cables. an also provide retrofit, auxiliary EMI attenuation. EXMPLE PPLITION d down (relative to baseline noise) MP HP MP Frequency EXMPLE PPLITION GRPH EXPLNTION: The zero line on the graph represents the base line noise recorded for an unprotected microprocessor. The curve (d down) represent the performance of the Laird Technologies ferrite plate relative to the baseline. The addition of the ferrite plates to the top of the processor in this specific application exhibits up to a 5 d EMI reduction relative to the unprotected part. Performance can vary with different sizes, materials, processors and applications.
