Eccosorb™ RF-LW

Eccosorb™ RF-LW

Light Weight EMI Noise Suppression Absorber

Product Description

Lair Laird has developed a new family of absorbers which can offer game-changing performance at lower frequencies.  This group of elastomeric materials utilizes a proprietary filler system that produces an absorber with higher permeability and permittivity over standard magnetic fillers.  The filler system is inherently corrosion resistant and can pass the ASTM B117 salt fog requirements.  This family of absorbers provides the highest level of attenuation available for cavity resonance problems and surface current attenuation, while offering significant weight and thickness savings over traditional magnetic fillers below 6 GHz.

Features and Benefits

  • Industry best sub 6 GHz attenuation
  • Corrosion Resistant
  • Low outgassing properties
  • Weight and thickness reduction in application
