The 3M CN3190 1” X 1.5”-100 is widely used in various electromagnetic shieldings. In this article, we will discuss the application fields and working principles of the 3M CN3190 1” X 1.5”-100 in radio frequency interference (RFI) and electromagnetic interference (EMI) shielding and absorbing materials.

RFI stands for radio frequency interference. This subset of EMI stands for electromagnetic interference. It’s a disruptive line-of-sight transmission medium. If you’ve ever heard noises in a TV or radio station, it’s likely caused by RFI. Its sources can be due to power lines, electrical wiring, and other man-made objects. RFI is typically noticeable in the shortwave or broadcast radio frequencies.

The 3M CN3190 1” X 1.5”-100 is an absorber material that is often used to dissipate potentially harmful electromagnetic waves. It works by absorbing the threatening electromagnetic radiation and converting it into harmless thermal energy, thus protecting the user from the impacts of the radiation.

The 3M CN3190 1” X 1.5”-100 is particularly useful in the EMI shielding and absorbing industry. It can provide an effective shield against microwaves and transient electrical spikes, like those experienced in lightning strikes. This absorber material is particularly versatile and can be used to protect a wide range of equipment and personnel from electromagnetic interference.

In applications requiring shielding from frequencies ranging from 5GHz and above, the 3M CN3190 1” X 1.5”-100 is often used. It can also be used in high-frequency applications up to 18GHz. It also offers excellent thermal protection and can be used to prevent equipment from overheating due to long operations. Additionally, the foam has perforations, designed to provide extra absorption of electromagnetic energy.

The 3M CN3190 1” X 1.5”-100 also enhances the strength and efficacy of other EMI shielding materials. It is widely used in combination with conductive materials, such as aluminum, to shield and absorb electromagnetic radiation. This material can also be used to construct special doors and walls for sensitive or confidential areas, to ensure that no electromagnetic radiation escapes or enters the area.

The 3M CN3190 1” X 1.5”-100 is also used in automotive, medical, and military applications. It is especially useful in automotive applications, as it prevents electrical interference from compromising the performance of the vehicle. The foam is also used in medical applications, mostly to shield radiological equipment from potentially dangerous radiations. In military applications, the foam is used to shield electronic components used in communication and signal weapons from electromagnetic interferences.

All in all, the 3M CN3190 1” X 1.5”-100 is an effective RF and EMI shielding and absorbing material. It can be used to protect a wide range of equipment and personnel from the dangers of electromagnetic radiation. Additionally, the foam is highly versatile and can be used in combination with a variety of materials. Its applications are numerous and range from automotive to medical and military.
