Eccosorb™ RF-LB

Eccosorb™ RF-LB

EMI Noise Suppression Absorber

Eccosorb™ RF-LB is a silicone based elastomeric absorber with an improved low frequency filler system.  The proprietary filler system provides higher permeability than standard Eccosorb™ magnetic sheet materials, with a higher temperature limit than standard near field noise suppression absorber products.  Eccosorb™ RF-LB is used to suppress unwanted energy coupling and resonant or surface currents that cause EMI issues.

Features and Benefits

·        High Permeability

·        Excellent EMI suppression for lower frequency applications

·        High Temp near field noise suppression suitable for automotive applications

·        Suitable for suppression of cavity resonances and surface currents

·        Flexible

·        Dust free

·        UL94 H-B

·        REACH and ROHS compliant
