Eccosorb™ JCS-Next is a dielectrically loaded silicone absorber specifically engineered for high-frequency applications above 30 GHz. The material is designed to suppress cavity resonances, reduce EMI issues and absorb unwanted electromagnetic energy in advanced mmWave systems. According to Laird, its proprietary filler system is two to three times more effective than traditional dielectric or carbon-loaded absorber materials at high frequencies.
The silicone-based construction is waterproof and designed to perform reliably across extreme temperatures. Unlike many traditional absorbers, JCS-Next does not flake or shed particles, making it ideal for sensitive RF and microwave assemblies. The material can be die-cut into complex shapes and is available in thicknesses from 0.25 mm to 3.05 mm to support a wide range of design requirements.
