EFX(03)-240X240T0800 Datasheet/PDF RF interference (RFI) and electromagnetic interference (EMI) shielding and absorbing materials are materials used to block or reduce the shelter or absorption of RF radiation and EMI. In this article, we will take a look at one specific type of RFI and EMI shielding and absorbing material – EFX(03)-240x240T0800 material – and discuss its usage, application fields, and its basic working principles.
Usage and Application Fields
EFX(03)-240x240T0800 material is a non-flammable product with excellent shielding and absorption performance. It is mainly used for the shielding and absorption of medium-frequency and high-frequency electric waves/signals, and specifically to shield the external interference from the electronic products and protect the whole system from excessive radiations. This material is widely used for various types of electronic systems, including mobile communication devices, computers, telephones, walkie-talkies, TV sets, household appliances, radar systems, and navigation/GPS devices.
Working Principle
EFX(03)-240x240T0800 material emits high-frequency electric field and attenuates the received electric wave signals, thus preventing those signals from causing interference to the internal parts of electronic products. It is made up of a variety of components including a conductive metal film, non-woven material and conductive elastomer. It works in two ways – it either blocks the interference from the outside by having a thin layer of metal conductors on the surface of the EFX(03)-240x240T0800 material that shields the internal parts from the external electric waves, or it absorbs the electric wave signals efficiently and converts them into heat energy. This material is also capable of shielding against magnetic fields, as the metal paper emit “magnetic shielding” which diverts the magnetic fields from interfering with the internal parts of the electronic device.
Conclusion
EFX(03)-240x240T0800 material is a useful tool for minimizing RF interference and electromagnetic interference in electronic systems and devices. It emits a high-frequency electric field which blocks or absorbs the electric wave signals from causing any harm to the internal parts of the electronic device. It is widely used for mobile communication devices, computers, telephones, walkie-talkies, TV sets, household appliances, radar systems, and navigation/GPS devices.
