.RFI and EMI - Shielding and Absorbing Materials play an essential role in providing reliable electrical performance and signal integrity.
The 5-CN4490-1/2S is a type of absorptive material that is designed to effectively shield and absorb radio-frequency interference from equipment and systems. This material is highly effective in its ability to absorb and attenuate electromagnetic interference (EMI). It can be used in a wide variety of applications, from military to commercial, in the form of shielding and absorbing materials.
The main purpose of 5-CN4490-1/2S is to protect sensitive electronic equipment from interference caused by nearby RF transmitter devices. The material is able to block and absorb both electromagnetic fields generated by high frequency transmission signals and radiations. It also ensures signal integrity and helps to reduce unwanted “noises” or interference that may cause equipment malfunction.
The material is consists of a single sheet containing two sides. One side permeable to electromagnetic radiations, while the other side is an impermeable layer cut from a piece of sponge material. The impermeable sponge layer will shield and absorb the radiation emitted. The conductive side of the material works to direct the radiation away from its original source and into a more desirable direction. In addition, it also helps to keep the signal integrity intact.
5-CN4490-1/2S is commonly used in military applications because of its effective and reliable performance. It is used in the production of ammunition, missiles, drones, aircrafts, submarines, and other military equipment. It also can be found in many commercial applications such as consumer electronics, telecommunications, medical devices, and more.
As for its working principle, the material absorbs and attenuates the unwanted energy generated by the nearby RF transmitter. The sponge material will absorb the energy and the conductive side will funnel it away. The combination of both layers is designed to effectively reduce the amount of interference and provide reliable electrical performance.
In conclusion, 5-CN4490-1/2S is a shielding and absorbing material that is highly effective in providing reliable electrical performance and signal integrity. It is designed to effectively shield and absorb RF interference and reduce the amount of electromagnetic radiation. This material can be used in a variety of applications, such as military and commercial, to protect sensitive equipment and ensure signal integrity.
