RFIs and EMI - Shielding and Absorbing Materials

Shielding a product against RFIs and EMI is the most effective way of protecting it against interference during operation. Effective shielding entails forming a tightly-bound ‘bubble’ around the product by using high-performance materials with specialized capabilities. The most widely used types of materials for shielding and absorbing RFIs and EMI are metallic and dielectric materials.

Metallic Materials

Metallic materials are those made of or containing a metal, such as copper, aluminum, stainless steel, nickel, and silver. They are used for shielding because of their high electrical conductivity and their capability to reflect and absorb electromagnetic radiation over a broad frequency range. Metallic materials are also highly effective at preventing electrostatic discharge from entering or leaving the interior of an enclosed area. Metallic materials are available in many forms, including magnetically-permeable alloys and thin-film foils.

Dielectrics Materials

Dielectrics materials, on the other hand, are non-conductive materials that can absorb and prevent transmission of EMI and RFI. Examples include plastics, rubber, ceramics, fiber composites, foams, and woven cloths. Due to their non-conductive and non-magnetic properties, dielectrics materials are suitable for products that cannot use metallic materials. They are also used in conjunction with metallic materials to improve the performance of the shielding system.

Applications of 55005146

55005146 is a lightweight optical grade laminate film designed to provide shielding and absorption of microwave and RF signals. It is a versatile material used in applications across a broad range of industries, from computer and consumer electronics to telecommunications, automotive, aerospace, military, and industrial applications. This laminate film is available in a variety of thicknesses and in several variants to suit different applications. It can provide shielding up to 80+ dBs at 2.44 GHz, and is highly effective in preventing EMI/RFI interference.

Working Principle of 55005146

The 55005146 works by reflecting and absorbing electromagnetic energy from outside sources. Its laminated construction contains an inner metal layer that reflects incoming EM energy, while an absorptive layer on the outside absorbs any EM energy that penetrate the outer layer. This creates an effective shield against any EM radiation that is present in the environment.

When the material is placed between two objects, such as a computer and a monitor, it prevents EMI and RFI from traveling between the two. This is because the metal component of the laminate shields the electrical signals from passing, while the absorbent layer absorbs any EM energy that does pass through and prevents it from entering the interior of the device.

The 55005146 is also highly fire retardant and meets all industry standards for flammability and smoke generation.

Conclusion

The 55005146 is a lightweight and versatile optical grade laminate film designed to shield electromagnetic radiation in a wide variety of applications. It is highly effective at preventing interference from EMI and RFI, and can provide shielding up to 80 dBs at 2.44 GHz. The laminate film’s construction contains an inner metal layer for reflection and an outer absorbent layer for absorption, providing an effective shield against any EM radiation that is present in the environment. The 55005146 is also highly fire retardant and meets all industry standards for flammability and smoke generation, making it a great choice for many applications.
