3-6-1125

RFI and EMI - Shielding and Absorbing Materials is a large category of materials that can provide protection from electromagnetic interference (EMI) and radio frequency interference (RFI). Shielding materials act as a barrier to prevent EMI and RFI from entering a system or structure, while absorption materials can reduce the impact of such EMI and RFI beyond the barrier. 3-6-1125 is a multi-functional shielding material that combines properties of both shielding and absorption materials to address a variety of application needs.

3-6-1125 functions as a three-layer composite material system comprised of a conductive metal layer, dielectric insulation layer, and absorber layer. The insulation layer functions to provide electrical and mechanical integrity to the system while keeping the layers separate. The absorber layer functions as a broadband absorber to diffuse the electromagnetic waves over a wide frequency range. The conductive metal layer is a combination of steel wire mesh or expanded metal and perforated sheet with high permeability properties. This combination allows for higher shielding effectiveness than either material would have on its own.

3-6-1125 is widely applicable in multiple industries, including automotive, aerospace, medical, and electronics. In the automotive industry, it is used to shield airbag deployment circuits from external EMI. In the aerospace industry, it is used to protect avionic systems from lightning and power line conducted EMI. In the medical industry, it is used to protect sensitive electronics from ambient RF radiation. In the electronics industry, it is commonly used as a within-enclosure shield.

The working principle of 3-6-1125 is relatively straightforward. Its three layers work together in a synergistic way to reduce both conducted and radiated EMI impedance, and the metal layers provide excellent attenuation of high frequencies. The outer layers of the composite material create an effective Faraday cage which blocks EMI from entering the interior. The insulation layer keeps the composite material strong and rigid, and it also acts as a dielectric material separating the different metal layers to stave off possible short-circuiting.

3-6-1125 is also highly adjustable to fit various applications. The outer layers of the composite material can be tailored according to user requirements to maintain a specified level of shielding effectiveness over a range of frequencies. The total thickness of the composite material can also be adjusted to suit the application; thicker materials work better for higher frequencies, while thinner materials work better for lower frequencies.

3-6-1125 is a versatile shielding material that can provide superior protection from EMI and RFI for a variety of applications. Its combination of a conductive metal layer, dielectric insulation layer, and absorber layer ensure a highly effective Faraday cage which blocks any external conductive or airborne interference. Furthermore, its adjustable nature allows it to be tailored to fit specific needs.
