eccosorb? jcs high loss, low density, flexible, carbon-loaded, silicone rubber sheet americas: +1.866.928.8181 europe: +49.(0)8031.2460.0 asia: +86.755.2714.1166 www.lairdtech.com flexible carbon-loaded silicone rubber sheet eccosorb jcs is a carbon-loaded, silicone rubber sh eet. it obtains its microwave properties via a carbon loading system and is therefore electr ically conductive. eccosorb jcs is waterproof and has excellent thermal characteristic s, tolerating high and low temperatures. low out-gassing is assumed, but formal testing has not been completed yet. material does not flake or shed. complex shapes are best cut with a water jet system. features and benefits ? high loss ? low density ? very flexible ? dust free ? high frequency applications markets ? automotive ? telecom ? industrial specifications typical properties eccosorb jcs frequency range 6 C 100 ghz service temperature c (f) -70 to 177 (-94 to 350) thickness 0.50 mm - 3.18mm (0.020-0.125) color black data for design engineer guidance only. observed pe rformance varies in application. engineers are reminded to test the material in appl ication. electrical properties eccosorb jcs is a pure dielectric absorber with no magnetic properties (permeability = 1). the complex permittivity varies with frequency, see graphs below. attenuation is a figure of merit for the lossiness of absorbent material and s hould not be used to directly estimate insertion loss. insertion loss is defined as the reduction in energ y between point a and point b caused by the insertion of a material. in general, insertion loss is a function of the material electromagnetic parameters and the thickness. jcs can be custom tailored to many different insertion loss values. attenuation (db/cm) 3 ghz 10 ghz JCS-3 2 3.5 jcs-5 4.5 9 jcs-7 8 16 jcs-9 10 20
