RFIs (Radio Frequency Interferences) and EMIs (Electro Magnetic Interferences) are both serious concerns in modern industry. Without shielding and absorption materials, these types of interference can damage delicate electronics, cause operational disruptions, and even pose a significant public safety risk. 5-CN4190-3/4 application field and working principle are two important methods to protect against RFI and EMI.

5-CN4190-3/4, also known as polypropylene-based metallized non-woven, is a flexible shielding and absorption material that can be used in a variety of applications. It is made from a thermally bonded spunbonded polypropylenewoven fabric that has been metallized with conductive particles. The particles on the surface of the 5-CN4190-3/4 create a Faraday cage, which blocks RF and EMI from entering the protected area. Additionally, the fabric underneath also absorbs most of the energy of the interferences, preventing them from reaching the protected equipment.

The 5-CN4190-3/4 has a broad operating range from -60 °C to +105° C (-76 °F to 221° F) and offers excellent resistance to chemicals, UV-light, and abrasion. It has been tested according to the following standards: UL 1703, EN 6152, EN 60825, ASTM D-1125, and F-1125. It also meets the stringent requirements of MIL-STD-1344, which means it can be used for the most critical military applications.

The most common application for 5-CN4190-3/4 is in the automotive industry, where it is used for shielding and absorption of RF and EMI. It is also used in aircraft, marine vessels, and many other industrial applications, such as broadcasting, telecom, and medical equipment. Due to its flexibility and low profile, it can also be used in consumer electronic products, such as smartphones and tablets.

In addition, 5-CN4190-3/4 is also widely used in shielding and absorption applications for EMI and RFI. The working principle of 5-CN4190-3/4 is based on the concept of a Faraday cage, which is an electrostatic shield that surrounds the protected area and prevents interference from entering. The shield is made of a conductive material, such as the metallized particles on the 5-CN4190-3/4, which attract and conduct the energy of the interference away from the protected area. Additionally, the woven fabric underneath also absorbs the energy of the interferences, preventing them from reaching the protected equipment.

In conclusion, 5-CN4190-3/4 is a versatile shielding and absorption material that can be used to provide protection against RFI and EMI. It is suitable for a variety of applications, from automotive to consumer electronics, and its high-performance capability meets the requirements of the most demanding applications. The working principle of 5-CN4190-3/4 is based on the concept of a Faraday cage, which prevents interference from entering the protected area by attracting and conducting it away and absorbing most of the energy.
