221 EMI Gaskets Fabric-over-Foam Innovative Innovative TTechnologyechnology for a for a Connected Connected WorldWorld UL 94HB RATED NI/CU POLYESTER TAFFETA FABRIC-OVER-FOAM Laird Technologies Fabric-over-foam (FoF) 221 EMI gaskets provide excellent EMI shielding performance for customers where EMI issues occur. The 221 series EMI gaskets are composed of electrically conductive fabric wrapped around a thermo-plastic elastomer (TPE) core. They are supplied with either a conductive or non-conductive pressure sensitive adhesive (PSA), and can be equipped with an Extended Release Liner (ERL) on the adhesive. The 221 is a UL 94HB rated product that can be created with cross-section profiles such as rectangle, D, knife, bell shapes, and others. The 221 EMI gaskets can be further customized to an application by die-cutting, hole punching, notching, etc. FEATURES MARKETS Fabric-over-Foam gaskets are RoHS compliant Cabinet applications UL 94HB LCD and Plasma TV Low surface resistivity of < 0.07 / Medical equipment provides excellent conductivity Servers Shielding effectiveness of >100 dB across a Printers wide spectrum of frequencies Laptop computers Extremely low compression forces allow for Networking equipment use of lighter materials Desktop computers Fabric is highly conductive to provide good Telecommunications cabinets EMI shielding and grounding Abrasion resistant metallized fabrics FORCE/DISPLACEMENT/RESISTANCE (FDR) show virtually no degradation in electrical 0.1 performance after 1,000,000 cycles 5 0.08 Laird Technologies proprietary coating 4 prevents fabric fraying and fingerprinting 0.06 Available with conductive or 3 non-conductive PSA 0.04 2 Many cross-section profiles available such as 0.02 rectangle, D, knife, bell and more 1 Profile gaskets can be cut to specified lengths, 0 0 kiss-cut on release liner, or mitered to form 0% 5% 10% 15% 20% 25% 30% 35% 40% 45% 50% frame configurations % Compression SHIELDING EFFECTIVENESS (dB) 140 120 100 80 60 40 20 global solutions: local support TM 0 1.00E+04 1.00E+05 1.00E+06 1.00E+07 1.00E+08 1.00E+09 USA: +1.866.928.8181 Frequency Hz Europe: +49.0.8031.2460.0 Asia: +86.755.2714.1166 www.lairdtech.com Effectiveness (dB) Resistance (ohms/inch length) Force (lbs/inch length)221 EMI Gaskets Fabric-over-Foam Innovative Technology for a Connected World Item Unit Value Test Method Shielding Effectiveness at 100 MHz 108 SAE-ARP-1705(Mod.) at 1 GHz dB 110 (W10 mm x H8 mm) Surface Resistivity / < 0.07 ASTM F390 Compression Set % < 20 ASTM D3574 Operation Temperature C -40 ~ 70 - Flame Retardant UL 94HB (UL file No.E170327) Hazardous Substance Compliant with RoHS (Directive 2011/65/EU) Antimony-free Shelf Life 12 months at 23C/ 60% R.H.
