Eccosorb™ RF-LB  

EMI Noise Suppression Absorber  

LAIRD™ ECCOSORB™ RF-LB  

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.

 

Ecco

sorb™  

RF-LB is used to suppress unwanted energy coupling and resonant or surface currents that cause EMI issues.

APPLICATIONS  

•

Eccosorb

TM

RF-LB series absorber can be placed over CPUs, main chip sets and other memory, and  

power IC devices to suppress radiated noise causing interference with RF functions, crosstalk or  

SAR emissions.  

•

•

•

It can be used to suppress noise currents from circuit trace lines and flat cables that act like  

radiating antennas causing EMI problems and crosstalk issues.  

It can also be applied to high-speed transmission lines, LCD displays and circuit board elements  

that are radiating energy and causing EMI issues.  

When placed within a cavity that is operating in the lower microwave frequencies, Eccosorb

TN

RF-  

LB series has proven to be effective in damping resonances and reducing surface currents.
