RFI and EMI shielding and absorbing materials are highly important for reducing the noise both in signal and power transmission lines. Materials used for such shielding and absorption can be divided into two broad categories, broadly referred to as electromagnetic absorbers and shields. The 0.375-5-CN4490 is an example of an absorber type of material, which is used for attenuation of the EMI radiation.

The 0.375-5-CN4490 is mainly used in industrial and biomedical applications, where it is used to reduce electromagnetic radiation from equipment such as machines, computers, and medical devices. It is also used in computers, communication systems, and digital multimedia. The 0.375-5-CN4490 is an effective material for making EMI protective shields, which are used to reduce electromagnetic interference (EMI).

The material can provide effective shielding or absorption of EMI radiation in the frequency range from 10 MHz to 5 GHz. This range of frequencies covers most of the telecommunication bands. The material provides excellent protection against EMI radiation from electronic devices.

The 0.375-5-CN4490 consists of a lightweight fabric covering a multi-layered structure of non-linear conductive materials. It is composed of two layers of flexible polypropylene with a filler layer of carbonized graphite powder sandwiched between them. The filler layer helps to absorb the high frequency electromagnetic induction, while the fabric makes the material resistant to mechanical shocks and abrasion.

The working principle of the 0.375-5-CN4490 is based on the electromagnetic induction effect. This effect occurs when an alternating electromagnetic field is irradiated onto the material. This field produces eddy currents in the material, which then induce a voltage in the material. This voltage is then dissipated as heat.

The 0.375-5-CN4490 offers a number of advantages, such as high attenuation of EMI radiation, good RFI noise reduction, low weight, and good electrical insulation. It is also highly adaptable and easy to install. Moreover, it can be used in a wide range of applications, such as cellular phones, WLANs, high-speed modems, and satellite antennas.

In summary, the 0.375-5-CN4490 is an effective and versatile material for reducing EMI and RFI radiation in industrial and biomedical applications. It works on the principle of electromagnetic induction and provides excellent protection against EMI and RFI radiation. It is also light weight, adaptable, and easy to install.
