Within the world of RFI and EMI, shielding and absorbing materials play a critical role in improving the performance of electronic devices by reducing the impact of signals from the outside world. The 3M CN3190 CIRCLE-0.625”-250 is one of the top performers on the market, designed to provide resistance, shielding, and absorbing properties in a single product. In this article, we\'ll look at the application fields and working principles of this product.

Applications

The 3M CN3190 CIRCLE-0.625”-250 is designed to be installed onto the circuit board for use in various applications. Its excellent shielding and absorption properties ensure that unwanted noise and interference remain outside the system, ensuring that the correct signals are transmitted in a timely manner. Common applications of this product include:

• High-frequency filters
• EMI shielding
• Power supply filtering
• Vibration reduction
• Heat dissipation

The 3M CN3190 CIRCLE-0.625”-250\'s ability to protect against EMI, noise, and vibration makes it suitable for use in a wide range of wide area networks (WANs), local area networks (LANs), and fiber optics. It is also commonly used in military equipment, medical devices, and telecom towers.

Working Principle

The 3M CN3190 CIRCLE-0.625”-250 utilizes a three-way shielding system to provide maximum protection against EMI, RFI, and vibration. The product consists of a copper-clad laminate, a metal-coated EMI gasket, and a metal-foam-based heat-dissipation material. These components work together to provide resistance, shielding, and absorption properties for the circuit board.

The copper-clad laminate provides the same electrical and thermal properties as a printed circuit board, while the EMI gasket layer provides shielding protection against EMI and RFI. The metal-foam-based material acts as an absorber, dampening unwanted noise and vibration signals from the outside world.

The 3M CN3190 CIRCLE-0.625”-250\'s unique three-way shielding system provides unparalleled protection against noise, interference, and vibration. It is light, durable, and widely used in a variety of applications.

Conclusion

The 3M CN3190 CIRCLE-0.625”-250 is a top-tier product offering superb protection against noise, EMI, and vibration. Its ability to provide resistance, shielding, and absorption properties make it suitable for a range of electronic applications, from WANs and LANs to telecom towers and medical devices. The product\'s three-way shielding system ensures superior protection in all environments.
