The facts about... Flat Sheet Absorbers
Flat sheet absorbers are used in products to prevent emission resonances and to suppress EMC (electromagnetic compatibility) problems...
Visit out sister website and read more.

Global EMC offer two types of carbon loaded flat sheet absorbers.


There is a flat single sheet type for specific frequency use and a multi layered type for more broadband applications.


The thin absorbers can be cut or die stamped, we can produce flat sheet absorber components.


All products can be painted or unpainted as required.


The table below is for optimised use however in a shielded product the performance and damping effect can be many times greater.
