The 3M CN3490 CIRCLE-0.938"-250 is a shielding and absorbing material designed to provide protection from EMI (electromagnetic interference) and RFI (radio frequency interference). This material is a composite that consists of a conductive base, an electrically charged layer, and a shielding material. The base layer provides a physical barrier from electrical signals, the electrically charged layer absorbs the EMI and RFI, and the shielding material prevents it from radiating outward. It is designed to maintain maximum shielding effectiveness, even in the presence of highly variable environmental conditions such as humidity, temperature, etc.

The 3M CN3490 CIRCLE-0.938"-250 is commonly used in industrial, aerospace, and automotive applications. In the automotive industry, it is used for shielding the engine compartment from noise and emissions. In the aerospace industry, it is used for reducing cockpit noise levels and protected sensitive equipment from EMI and RFI. In the industrial field, it is used for protecting critical industrial devices from electrical interference. It can also be used for shielding sensitive medical equipment, computer systems, and electronic components.

The working principle of the 3M CN3490 CIRCLE-0.938"-250 is based on the concept of Faraday cages. A Faraday cage is an enclosure made from a conductive material that blocks out EMI and RFI. When an EMI or RFI signal enters the cage, it is forced to follow the conductive surface, which dissipates its energy and prevents its radiation. The unshielded device is then effectively shielded from the external interference.

The 3M CN3490 CIRCLE-0.938"-250 is a highly effective material for EMI and RFI shielding and absorbing. It has an operating temperature range from -40°C to +105°C, making it suitable for use in a variety of environments. It is flame retardant and UL listed. It is also highly durable, with a shelf life of up to 8 years. In addition, it is extremely cost-effective, making it a great choice for a wide range of applications.
