RFIs and EMI shielding and absorbing materials are used to protect electronics and other similar equipment from electromagnetic interference. They can be used to either absorb, block, or reduce the amount of electromagnetic radiation coming from sources such as cell towers, power lines, and other electronic devices. 21164280 application field and working principle is an important factor when considering the necessary RFIs and EMI shielding material for a particular application.

Radio Frequency Interference (RFI)

RFI is the interference of radio frequencies with the operation of other electrical machinery. RFI can be caused by several sources such as radio transmitters, cell phones, power lines, and other electronics. It can cause malfunction, reliability issues, and data corruption or loss in electronic equipment. The effects of RFI can be minimized by using RFIs and EMI shielding and absorbing materials.

Types of RFIs and EMI Shielding Materials

RFIs and EMI shielding and absorbing materials can be divided into three main types: physical shielding, electromagnetic shielding, and absorptive shielding.

Physical Shielding

Physical shielding is the most common type of RFIs and EMI shielding material and consists of physical barriers, such as metal foil, metal screen, or perforated foam sheets. These materials are used to physically block the transmission of RFI and EMI.

Electromagnetic Shielding

The second type of RFIs and EMI shielding material is electromagnetic shielding. This type of material is designed to absorb the electromagnetic fields generated by RFI and EMI. Materials such as conductive fabric, carbon loaded plastics, and conductive coatings can all be used as effective electromagnetic shielding materials.

Absorptive Shielding

The third type of RFIs and EMI shielding material is absorptive shielding. This type of material is designed to absorb the energy of the emitted RFIs and EMI waves and thus reduce their intensity. Examples of absorptive materials include foams, gels, and rubber sheets.

21164280 Application Field and Working Principle

21164280 is an absorptive shielding material. It is made from a polyethylene foam blend which has been loaded with carbon particles. The carbon molecules absorb the energy of the RFIs and EMI waves, reducing their intensity and thus improving the overall performance of the equipment. It is especially well-suited for applications which require minimal interference with the equipment’s signal.

Conclusion

RFIs and EMI shielding and absorbing materials are an important tool for protecting electronic equipment from interference. 21164280 is an effective absorptive shielding material which is well-suited for applications which require minimal interference with the equipment’s signal. By understanding the different types of RFIs and EMI shielding materials available and their respective applications, engineers can ensure that their equipment is adequately protected from interferences.
