RFI and EMI - Shielding and Absorbing Materials

RFI and EMI Shielding and Absorbing Materials are key components in the protection of sensitive electronic equipment. In a rapidly changing industrial and corporate landscape, shielding materials are finding greater use and importance. The 3M CN4190 2”SQ-100 is a shielding material that is both effective and reliable.

The CN4190 is made from specialized acoustic foam combined with a highly conductive metal layer. The foam allows air to pass-through while still blocking noise, RFIs and EMI. There is also a choice between a semi-conductive foam or a non-conductive foam depending on the application requirements. The metal layer provides an extra layer of RFI and EMI protection.

It is most often used in military and aerospace applications due to its high shielding performance and its ability to deal with extreme temperature changes. It is also used in commercial applications including industrial control systems, medical imaging systems, telecom networks and automated test equipment.

The working principle behind the CN4190 is simple and effective. It employs a combination of materials to block and absorb the RFI and EMI signals. The combination of the metal layer and the foam has been specifically designed to work together to absorb the frequency band emitted by the waveform. It has been tested and certified by the IEC 61000-4-4 standard for shielding materials.

The CN4190 is a sturdy and reliable shielding material which ensures a streamlined operation in various environments. It is able to handle extreme temperatures and harsh environments without any degradation or damage. It also has an incredibly low profile, making it suitable for tight spaces and constricted areas. It is non-flammable, non-toxic and can be easily cut to fit any size or shape.

In conclusion, the 3M CN4190 2”SQ-100 is an ideal solution for shielding and absorbing materials for applications requiring RFI and EMI protection. It offers reliable performance under varying conditions, high shielding performance and an easy installation. Its combination of metal and foam make it the perfect choice for RFI and EMI protection.
