Introduction to RFI and EMI - Shielding and Absorbing MaterialsRadiofrequency interference (RFI) and electromagnetic interference (EMI) are two forms of electromagnetic interference that can interfere with wireless signals and disrupt the operation of electronic circuits. RFI is usually caused by electromagnetic interference from radio waves, while EMI is typically caused by interference from nearby electronic equipment. In order to minimize the effects of these types of electromagnetic interference, it is important to use shielding and absorbing materials.5-CN4190-1/2 Application Field and Working Principle5-CN4190-1/2 is a shielding and absorbing material that provides protection against RFI and EMI. It is a two-sided conductive fabric which is coated with a special layer of conductive particles, such as copper, stainless steel, aluminium, or carbon steel. This conductive layer is designed to efficiently absorb and reflect electromagnetic radiation, thus providing good shielding performance against RFI and EMI. The material is also highly resistant to water, ultraviolet light, and most chemicals.In terms of RFI and EMI shielding, 5-CN4190-1/2 offers excellent performance. The conductive particles absorb the electromagnetic radiation, and the highly reflective surface reflects the radiation away from the sensitive equipment. This allows for effective attenuation or complete elimination of the interference.When used for EMI protection, the highly reflective surface of the material also helps to reduce the amount of electromagnetic radiation that is emitted by the source. This in turn reduces the interference with other electronic equipment that may be nearby.ConclusionOverall, 5-CN4190-1/2 is an excellent material for shielding and absorbing both RFI and EMI. The highly reflective surface provides excellent shielding against electromagnetic radiation, while the conductive particles absorb the electromagnetic radiation. This makes the material highly effective for eliminating interference with electronic equipment.
