With specialized technologies for developing various ferrite items to meet customer’s demands, Samwha has been manufacturing excellent ferrite absorbers (Flat and grid types).

Samwha ferrite absorbers show excellent absorbing performance, environmentally resistant qualities, high strength and good heat resistance.
So they can be widely used as anechoic chamber for electro-magnetic compatibility(EMC) testing or block against electromagnetic interference(EMI).
 
 
· Anechoic chamber for EMC Testing
  (Compact, 3m and 10m chambers, etc.)
· Radio-wave absorption for noise block like TV ghost by   Skyscrapers
· Improve communication environment (Ferrite powder as   material of rubber sheets)
 
 
· Broadband characteristics
Samwha ferrite absorbers show good absorption in the range of 30MHz~1GHz.
· Space efficiency
Due to thin thickness of ferrite absorbers, the volume which the absorbers installed in the anechoic chamber is greatly reduced.
· High power handling capability
Non-flammable characteristics of ferrite absorbers can be properly utilized for high power radiated immunity test.
· Easy installation
Ferrite absorber panels will be directly screwed on shielding enclosure which enables installation easily.
· Performance stability
For no physical degradation through years, Samwha ferrite absorbers have good performance stability.
 
 
 
   
 
Samwha produces excellent single type(SD) in the range of 30MHz to 400MHz.
The panel types(SFA) are easy to be built for anechoic chamber with lower cost than single types, under any circumstances.
