Radio frequency interference and electromagnetic interference, collectively known as RFI and EMI, are major obstacles to reliable and safe operation of electrical and electronic devices. Shielding and absorbing materials play an important role in reducing the impact of RFI and EMI on device performance. This article discusses the application field and working principle of the 78820249 material.

The 78820249 material is a highly effective and economical shielding and absorbing material, primarily used for elimination of electromagnetic and radio frequency interference in electronic products. It is a very thin, soft and flexible material that can be used to suppress EMI radiation from computers and other electronic devices. It provides a specific attenuation of EMI radiation in an order of 15 dB in the range from 30 to 2000 mHz.

The 78820249 material is commonly used in the consumer electronics, telecommunication, medical and automotive industries for shielding radio frequency (RF) and electromagnetic interference (EMI). It is ideal for electronic equipment, including Motorola radio transmitters, PDAs, PCs, cell phones, cordless phones, compact disks, TV receivers, satellite receivers, etc. It is also perfect for thermal insulation of various electronics products. The material is applicable for reducing the radiation effect of LED strips, as well as for vibration dampening of non-magnetic metallic products and antenna mounting.

The 78820249 material works by limiting the radiation of EMI energy by attenuating, reflecting and absorbing signals. It is constructed from a metal sheet laminated with a special RF-active material, which has very low surface resistivity and dielectric constant. The voids in between the metal sheets provide a thicker layer of insulation that keeps the energy contained and prevents RF energy from passing through. The absorption of EMI signals is further enhanced by the use of closely-spaced layers of metal and RF-active insulator, which reduce any resonance that would normally exist between the metal and the RF-active insulator.

The RF-active layer of the 78820249 material also acts to absorb the energy of an RF signal, preventing it from being re-radiated. This helps improve the signal-to-noise ratio of the electronic device, reducing the amount of interference caused by external sources. The material is also able to attenuate strong signals, helping to eliminate interference from nearby sources. In addition to shielding from EMI radiation, the 78820249 material also helps to contain generated or reflected energy, reducing the risk of harm to personnel or equipment.

The 78820249 shielding and absorbing material can be used in combination with other methods for further improving the performance of electronic systems. The 78820249 material can be used in conjunction with other materials such as ferrite cores, plastic films, honeycomb filters and electrically conductive fabrics, to provide additional shielding and absorption of EMI signals. The combination of several methods increases the overall effectiveness of the shielding and absorption, providing further protection from interference.

In conclusion, the 78820249 material is a highly effective, economical solution for eliminating radio frequency and electromagnetic interference in electronic products. It provides excellent attenuation of EMI radiation and also acts as a barrier, preventing external signals from affecting the electronic device. It is perfect for a wide variety of industries and applications, providing reliable shielding and absorption of EMI signals and helping to prevent interference from external sources.
