RFI and EMI - Shielding and Absorbing Materials

The CF720KA01000127 was created to shield electronics against radio frequency interference (RFI) and electro magnetic interference (EMI). It is a highly effective shielding and absorbing material that has a unique combination of electrical properties, chemical performance and environmental stability in order to provide superior protection.

Application Field

CF720KA01000127 is specifically designed for shielding current carrying equipment and is capable of attenuating exposed electric fields up to 75 dB. It is used to achieve reliable shielding of high voltage a.c. current circuits, to block higher frequency electronic signals, and as a barrier to related electronic noise generated by external sources.

It is extensively used in the industrial sector as well as in domestic and commercial deployments. It can be used in any equipment where the powered electronics require shielding from external noise and interference. Its performance is superior to that of standard galvanized steel or aluminum shielding.

Working Principle

The CF720KA01000127 operates by creating a barrier between the protected device lines, and the outside noise and interference sources. It is made of a combination of materials, with a double layer shell construction and a unique built-in thermal insulation. The layers are placed between two layers of a conductive material with a layer of thermal insulation in between. This combination of layers provides an effective radio frequency interference and electro-magnetic interference shield, while dissipating heat.

The materials used for the mesh shell are selected specifically for their electrical properties, chemical performance, and thermal insulation capabilities. The metal layers effectively reduce the level of noise and interference from the outside world, while the thermal insulation prevents heat transfer between the exterior and interior environment. This ensures a stable temperature distribution in the protected area.

The CF720KA01000127 is designed to eliminate RFI and EMI radiation, thereby reducing the risk of damage to the protected device. Its high performance shielding and absorbing materials ensure that any RFI or EMI produced by an external source is blocked from entering the protected area.
