SOFT-SHIELD 5000 Series EMI gaskets consist of an electrically conductive fabric jacket over a highly compressible foam core. The nickel-plated-silver woven nylon rip-stop jacket is self-terminating when cut. Chosen for its exceptional compressibility, the foam core typically requires less than 1 lb/in (0.175 N/mm) closure force, making it especially useful for thin-walled plastic enclosures. Property Test Method Typical Values Shielding Effectiveness CHO-TM-TP08 See graph above Compression Set ASTM D3574 (mod.) <25% Electrical Conductivity CEPS-0002 0.1 ohm/sq. (max.) Adhesive Peel Strength ASTM D1000 (90 Bend) 4 lb/inch (0.7 N/mm) (min.) Standard pressure-sensitive adhesive attachment tape (PSA) makes SOFT-SHIELD 5000 Series gaskets a user-friendly and cost-effective design solution. FEATURES Typically requires <1 lb/inch (0.175 N/mm) closure force - 5 times lower than other gaskets >90 dB attenuation from 20 MHz to 10 GHz Asymmetrical profiles as well as "C", "V", "P", "D" shapes* Self-terminating fabric jacket No performance degradation after 10,000 compression cycles Continuous lengths or kiss-cut parts on polyester film sheets UL 94V-0 rated versions available BENEFITS Cost-effective Custom lengths available Alternative to BeCu fingerstock gaskets Pick and place installation available Technical application support Global distributor/fabricator network *Call for availability SOFT-SHIELD(R) 5000 Series Conductive Jacket over Foam EMI Gaskets continued Use the following part number to order SOFT-SHIELD 5000 Series gaskets: 82 - A B C - X X X X X - Y Y Y Y Y Gasket profile (see below) Designates SOFT-SHIELD 5000 EMI gaskets A Jacket Type B PSA Tape Backing 1 Nickel-plated nylon rip-stop fabric 2 Other (to be assigned) C Gasket Service Rating 1 No PSA tape 2 PSA tape ,,, ,,, Length in inches x 100 ex., 09600 = 8 ft.
