EFA(03)-240X20MT0800

RFI and EMI shielding and absorbing materials are common components used in many sectors of the electronics industry. This article will provide an overview of the application field and working principle of EFA(03)-240X20MT0800, a popular option for RFI and EMI shielding and absorbing.The EFA(03)-240X20MT0800 is a multi-layered Faraday shield that consists of an outer sheet of copper with an inner layer of silver nanowires sandwiched between two additional layers of dielectric materials. The copper sheet provides the Radiated Field/Radiation-Induced Coupling (RF/RIDC) protection, while the silver nanowires form an array of nano- particles that provide the Electro-Magnetic Interference (EMI) shielding effect. This combination of passive shielding materials provides preventative protection from both radiated and conducted radiation, providing a high level of attenuation from a wide range of frequencies. The EFA(03)-240X20MT0800 has a high signal-to-noise ratio, is light in weight, and is cost-effective compared with other shielding materials. In addition, it is easy to install and provides shielding from the majority of frequencies in the 2.4 kHz to 18 GHz range. It can be used in both military and commercial applications, and is suitable for use in indoor and outdoor environments.The working principle of the EFA(03)-240X20MT0800 is based on its Faraday shielding effect. When an electromagnetic wave encounters a shield composed of conductive material, the wave is reflected by the surface of the shield. This reflection is caused by the electric field emanating from the conductive material. The electric field of the incident wave and the electric field of the shield interact, resulting in a cancellation of the incident wave. By reflecting the electromagnetic wave, the shield can provide high attenuation across the entire frequency range. In addition to the Faraday shielding effect, the EFA(03)-240X20MT0800 utilizes the absorption effect of its nano-particles to further reduce EMI levels. The nano-particles absorb incoming radiation and convert it into heat, thereby significantly reducing the incident radiation levels. Moreover, the shield’s multiple layers of materials provide additional benefit in that they direct the current, reducing the amount of radiation that is not absorbed. The EFA(03)-240X20MT0800 is a versatile, low-cost solution that is suitable for a variety of RF/RFI and EMI applications. It is easy to install and provides high attenuation at a wide range of frequencies. It can be used in both military and commercial applications, and is suitable for indoor and outdoor environments.
