RFIs and EMI are electromagnetic interferences that can cause electronic systems to malfunction. EMI is the unwanted electromagnetic energy generated by one or more devices, while RFI is a form of electrical interference that is unwanted in the environment. In order to achieve effective shielding and absorption of both RFIs and EMI, specialized materials with electromagnetic properties are necessary.
5-1345-3/4S: 5-1345-3/4S is an elastomeric polymer material that is designed for both EMI and RFI shielding, as well as absorbing electromagnetic energy. It is a three dimensional matrix structure composed of a high dielectric modified silicone matrix and conductive aluminum flakes of varying thicknesses. Due to its design, 5-1345-3/4S has very good EMI shielding performance at higher frequencies, without the need for additional copper shielding and other expensive metallic components.
Application Field: 5-1345-3/4S is suitable for a variety of electronic applications, such as in computer networks, data centers, industrial control equipment, automotive electronics, defense and military equipment, aerospace electronics, medical electronics, telecommunications and consumer products. It can be used to shield and absorb RFIs and EMI in a variety of systems, including high speed data lines, cabling, wiring, circuits, antennas, and high power emitting sources. Additionally, 5-1345-3/4S can also be used as insulation material and heat-proofing protection.
Working Principle: The functioning of 5-1345-3/4S is based on the principle of electromagnetic interference shielding. When EMI or RFI is present in the environment, 5-1345-3/4S will absorb the energy of the interfering waves, preventing them from reaching the sensitive equipment and preventing them from functioning properly. The elastomeric polymer material absorbs the energy of the waves by converting it into heat, which is then dissipated. Additionally, the conductive aluminum flakes also reflect a large portion of the wave energy, further ensuring that the sensitive equipment remains safe from interference.
In conclusion, 5-1345-3/4S is an elastomeric polymer material that is designed for both EMI and RFI shielding. Its three dimensional matrix structure is composed of a high dielectric modified silicone matrix and conductive aluminum flakes of varying thicknesses, allowing it to absorb and reflect high frequency RFIs and EMIs. It can be used to shield and absorb RFIs and EMI in a variety of systems, including computer networks, data centers, industrial control equipment, automotive electronics, defense and military equipment, aerospace electronics, medical electronics, telecommunications, and consumer products.
