51H EMI Gaskets Fabric-over-Foam Innovative Innovative T Technology echnology for a for a Connected Connected World World UL 94V0 RATED NI/CU POLYESTER TAFFETA FABRIC-OVER-FOAM Laird Technologies’ Fabric-over-foam (FoF) 51H EMI gaskets provide excellent EMI shielding performance for customers where EMI issues occur. The 51H series EMI gaskets are composed of electrically conductive fabric wrapped around a soft urethane foam 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 51H is a halogen-free, UL 94V0 rated product that can be created with cross-section profiles such as rectangle, D, C, P, T, knife, bell shapes, and others. The 51H 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 • Halogen-free per IEC-61249-2-21 standard • LCD and Plasma TV • UL 94V0 • Medical equipment □ • Low surface resistivity of < 0.07 Ω/ • Servers provides excellent conductivity • Printers • Shielding effectiveness of >100 dB across a • Laptop computers wide spectrum of frequencies • Networking equipment • Extremely low compression forces allow for • Desktop computers use of lighter materials • Telecommunications cabinets • Fabric is highly conductive to provide good EMI shielding and grounding FORCE/DISPLACEMENT/RESISTANCE (FDR) • Abrasion resistant metallized fabrics 8 0.5 show virtually no degradation in electrical 0.45 7 performance after 1,000,000 cycles 0.4 6 0.35 • Laird Technologies’ proprietary coating 5 0.3 prevents fabric fraying and fingerprinting 0.25 4 • Available with conductive or 0.2 3 non-conductive PSA 0.15 2 0.1 • Many cross-section profiles available such as 1 0.05 rectangle, D, C, P, T, knife, bell and more 0 0 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% • Profile gaskets can be cut to specified lengths, % Compression kiss-cut on release liner, or mitered to form frame configurations 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) 51H 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 Ω/ < 0.07 ASTM F390 Compression Set % < 20 ASTM D3574 Operation Temperature °C -40 ~ 70 - Flame Retardant UL 94V0 (UL file No.E170327) Hazardous Substance Compliant with RoHS (Directive 2011/65/EU) Compliant with SONY ss-00259 Halogen-free (based on IEC-61249-2-21) Antimony-free Shelf Life 12 months at 23°C/ 60% R.H.
