Mesh Performance

The performance of any RFI / EMC window is dependent on how well it is bonded to the equipment screen. The following tables show the screening capability of the mesh, where the mesh itself is clamped to the screen with no gaskets in between.

The shielding performance will improve as the window size reduces, due to the performance characteristics of the aperture. Mesh selection should be based on required performance and with the way that it interacts with your chosen display.
