The dielectric constant of these high frequency laminates is the lowest of all products, and low dielectric loss make them well suited for high frequency/ broad band applications where dispersion and losses need to be minimized. Because of its extremely low water absorption characteristics, RT/duroid 5880 laminates are ideal for applications in high moisture environments. RT/duroid 5880 laminates are easily cut, sheared and machined to shape, and resistant to all solvents and reagents normally used in etching printed circuits or plating edges and holes. RT/duroid 5870 and 5880 laminates have the lowest electrical loss of any reinforced PTFE material, low moisture absorption, are isotropic, and have uniform electrical properties over frequency.Rogers RT/duroid 5880 high frequency laminates are used in: commercial airline broadband antennasmicrostrip and stripline circuitsmillimeter wave applicationsmilitary radar systemsmissile guidance systemspoint-to-point digital radio antennasRogers RT5880 material in stock:   ModelParameterthickness(mm)Permittivity(ER)F4BF4B0.382.2F4B0.552.23F4B0.225,0.3,0.5,08,1,1.2,1.5,2,2.5,3.02.65F4Bk0.8,1.52.65F4B0.83.5FE=F4BM12.2RogersRO58800.254  0.508 0.7622.20 ± 0.02RO43500.254 0.508,0.8,1.5243.5RO40030.5083.38TACONICTLF-350.83.5TLA-60.254,0.8,1,1.5,2.65TLX-80.254,0.8,1,1.62.55RF-60A0.646.15TLY-50.254,0.508,0.82.2TLC-320.8,1.5,33.2TLA-350.83.2ARLONAD255C06099C1.52.55MCG0300CG0.83.7AD0300C0.83AD255C03099C0.82.55AD255C04099C12.55DLC22012.2
