RFI and EMI - Shielding and Absorbing Materials

The 3M CN4190 CIRCLE-1.5"-100 is a shielding and absorbing material part of a family of Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) shielding products. It is a cost-effective method for reducing radiated emissions in regulated applications, providing up to 65dB of shielding effectiveness from 10MHz to 10GHz. This versatile solution is designed to provide a simple and convenient way to meet FCC and other international EMC requirements for reducing electromagnetic radiation.The 3M CN4190 CIRCLE-1.5-100 shielding and absorbing material is an air-cored, conductive adhesive lamination tape with a pressure sensitive adhesive. It can be used in a variety of applications, including grounding, shielding, and preventing unwanted interference and interference with adjacent signals. It is ideal for applications in automotive, industrial, medical, and communications technology where high levels of electrical noise or RF energy can permeate.The conductive components of the 3M CN4190 CIRCLE-1.5-100 shielding and absorbing material have been engineered to provide maximum absorption of electromagnetic noise. The tiny air gaps created by the admixture of air and conductive adhesive limit the number of layers in the shielding and absorbing material needed to effectively block out RF radiation. This allows for the material to be used in environments where a higher level of RF shielding is required. The pressure-sensitive adhesive system allows for quick and easy installation of the shielding and absorbing material to a variety of surfaces.The conductive adhesive used to create the 3M CN4190 CIRCLE-1.5-100 shielding and absorbing material is applied in a controlled environment. This ensures uniform coverage over the conductive adhesive and minimizes any potential RF energy leakage, as well as providing an effective baffling layer that prevents interference between components installed with the material. The material is also designed to be reworkable, allowing for easy adjustments after installation.The 3M CN4190 CIRCLE-1.5-100 shielding and absorbing material is also designed to provide a Faraday cage effect, which helps to prevent electrostatic discharges (ESDs). The Faraday cage effect helps to reduce the impact of static electricity in environments where it would otherwise cause false alarms or incorrect readings. ESDs can cause significant damage to sensitive electronics, so this feature is invaluable for applications in industries such as medical, automotive, industrial, and communications.The 3M CN4190 CIRCLE-1.5-100 shielding and absorbing material can be used in combination with other RF and EMI shielding solutions. It is well suited for applications in which an internal shield is needed for electrical noise or RF energy protection. It can also be used in conjunction with external shielding solutions such as an RF absorber or an RF absorber cable shield. In applications with heated chambers, the 3M CN4190 CIRCLE-1.5-100 shielding and absorbing material helps to maintain safe temperatures.The 3M CN4190 CIRCLE-1.5-100 shielding and absorbing material is an effective shielding solution for reducing electrical noise and electromagnetic radiation. It is cost-effective and easy to install, allowing it to be used in a variety of applications. It can also be used in combination with other RF and EMI shielding solutions to create an effective shielding solution. The Faraday cage effect helps to prevent ESDs, and its reworkable design helps to ensure a perfect fit every time.
