Solutions for reducing RF and electromagnetic interference (EMI) and shielding and absorbing materials are rapidly becoming more important. This is especially true for applications involving technologies with increasingly small sizes, such as 3M CN4190 1/2” x 2”-100 shielding and absorbing materials. In this article, we will discuss the application fields and working principle of 3M CN4190 1/2” x 2”-100 shielding and absorbing materials. 3M CN4190 1/2” x 2”-100 shielding and absorbing materials are designed to be used in applications such as electronic enclosures, cell phone shieldings, and computer enclosures. This product is designed to protect devices and sensitive electronic components from electromagnetic interference (EMI) and RF radiation. The shielding and absorbing material reduces radiation that can interfere with wireless signals, making communication more reliable. The material has also been developed to shield and absorb more than 400 MHz of electromagnetic radiation, making it an ideal choice for shielding small and sensitive components. The material is made up of two distinct components. The first is a tin-plated copper outer shield which provides protection against most EMI. The second is an inner liner typically made from a copper-based material which has a higher absorption rate. This combination is designed to reduce EMI and RF radiation to levels which are not interruptive to electronic systems.The first layer of the 3M CN4190 1/2” x 2”-100 shielding and absorbing materials is intended to absorb any radiation which escapes the shielding. The material is designed to have a high attenuation rate at frequencies from 400 MHz to over 3 GHz. The material is made to absorb more than 95% of the radiation in these frequency ranges. The material is also designed to have an attenuation rate which remains constant in a frequency range from 400 MHz to 6 GHz. At frequencies over 6 GHz, the material will be less effective at attenuating radiation.The second layer of 3M CN4190 1/2” x 2”-100 shielding and absorbing materials is intended to address the issue of signal interference. The material is designed to provide an even higher attenuation rate than the first layer of material. Additionally, the material is designed to be very effective at reducing any noise generated at frequencies between 800 MHz and 3 GHz.To achieve the best results, both layers of the material should be used together. By combining the two layers, the shielding and absorbing materials can provide an effective solution for protecting electronics from EMI and RF radiation. The high attenuation rate of the material ensure that any noise generated at frequencies between 800 MHz and 3 GHz will be minimized, and any radiation which escapes the shielding will be significantly reduced. In conclusion, 3M CN4190 1/2” x 2”-100 shielding and absorbing materials are designed to reduce radiation and interference for electronic systems, particularly those in small devices. The combination of the two layers of shielding and absorbing materials can ensure that the radiation and interference are reduced to levels which do not interfere with the operation of electronic components. The material is designed to provide an effective solution for shielding and absorbing radiation, making it an ideal choice for protecting sensitive components.
