3M EMI/EMC Solutions

Electrically Conductive Cushioning Gasket Selections

(ECG): Single coated and double coated conductive foam products

(less than 1mm thickness)

(MSG): Very soft single coated conductive foam products with a metal carrier

(greater than 1 mm thickness).

(eCAP): Solid core single coated acrylic conductive gaskets with a

conductive fabric carrier (less than 1 mm thickness).

The 3M ECG series has two versions. The single coated version ECG-70xx and the double coated version

ECG-80xx. The 3M MSG products are available in greater than 1mm thickness with a metal carrier layer that

is either a metal foil or a magnetic foil type. The eCAP product 7830N is an acrylic conductive ECATT with a

conductive fabric carrier layer to make a single sided eCAP gasket product.

3M EMI Absorbers & 3M Grounding Solutions for Optimized Antenna Performance

3M EMI Absorbers and 3M ECATT Grounding Solutions (Conductive PSA ECATT, Conductive Foils & Fabrics)

provide for an optimized antenna performance solution. Absorbers reduce line of sight or reflected EMI noise

near an antenna, Conductive PSAs and Gaskets offer grounding for a thickness range potential of 0.03 mm to

3.3 mm gaps, to reduce stray flowing currents and associated EMI that degrades antenna performance (S/N).
