RFIs (Radio Frequency Interferences) and EMIs (Electromagnetic Interferences) are two of the common forms of electromagnetic pollution that can easily interfere with any electronic device. Shielding and absorbing materials play an important role in preventing these electromagnetic radiations from entering into electronic circuits and affecting their overall performance.

CN-3490 is one such shielding and absorbing material being used in many applications. It is made up of two adhesive layers where the top layer is composed of a conductive elastomer base material and the bottom layer is a conductive sheet. This makes CN-3490 an excellent solution to protect electronic devices from external sources of RFIs and EMIs. Aside from its shielding capability, it also offers excellent flexibility, thermal resistance, and corrosion resistance.

One of the primary applications of CN-3490 is for controlling radiations from cellular and wireless communication systems. In this application, the CN-3490 is used as a shield to protect the electronic circuitry from radiation emitted by cellular base stations and other wireless communication systems. It is also used for controlling audio interference from high-power audio equipment, radio, television, and other RF emission sources. Another application of the CN-3490 is for controlling interference signals in MRI machines, medical monitoring systems, and various sensitive measuring and calibration instruments.

CN-3490 is also used in automotive applications, where it helps protect the circuits of the engine, transmission, and other electronic components from electric and electromagnetic radiations, resulting in improved system efficiency and reliability. It can also be used to improve the effectiveness of noise and vibration control, and improve the sound quality of automotive components.

The working principle of CN-3490 is based on its combination of two layers of controlled adhesive material. The top layer is made of a conductive elastomer material, while the bottom layer is composed of a conductive sheet. When the CN-3490 is placed between two objects or between a source of interference and an electronic device, the outermost layer acts as an absorber, while the innermost layer acts as a shield. The elastomer layer effectively absorbs the incoming RFI and EMI and dissipates them into the atmosphere. At the same time, the conductive sheet shields the electrical component from the incoming interference.

CN-3490 is an effective solution for controlling RFIs and EMIs in numerous applications. Its combination of shielded and absorbing layers makes it an ideal solution for controlling the emission of radiations and interference caused by electronic equipment. Whether used for automotive applications, medical monitoring, or wireless communication systems, CN-3490 is a reliable shielding and absorbing material for any electronic component.
