3M 7100112738 Emi Shielding Absorber 100m Roll

Product Description

The 3M 7100112738 is an EMI shielding absorber tape supplied in a 100-meter roll under the AB6005S product line. It combines a high-performance alloy-filled polymer absorber layer laminated to an aluminum foil shielding layer, with insulation designed to prevent z-direction or direct conductivity. A non-conductive adhesive backing holds the assembly together. The construction is thin and flexible, allowing it to be die cut to custom shapes. Electronics technicians and PCB assembly professionals use this material to manage electromagnetic interference in densely packed electronic assemblies.

This absorber roll is suited for residential and commercial electronic component manufacturing, circuit board shielding, and EMI-sensitive device assembly. The laminate design delivers both absorption and shielding in a single material, reducing the need for multiple layers. It performs well in compact enclosures where space constraints limit conventional shielding options. The absorber layer helps minimize wave reflection, reducing EMI re-radiation within the assembly.

Key Features

• Alloy-filled polymer EMI absorber layer minimizes wave reflection and re-radiation
• Aluminum foil shielding layer laminated to absorber for combined EMI management
• Insulated construction prevents z-direction and direct conductivity
• Non-conductive adhesive backing for secure placement without grounding concerns
• Thin and flexible construction supports die cutting to custom shapes
• 100-meter roll length reduces material handling frequency in production environments

Compatibility

Designed as a general-purpose EMI absorber and shielding tape for use in electronic component assemblies, PCB layouts, and enclosed electronic devices where EMI absorption and foil shielding are required in a single laminate.

Installation Notes

Installation is typically performed by electronics technicians or PCB assembly personnel in a production or field-service environment. Power down and discharge any equipment before applying the tape to internal components or circuit boards. Clean and dry the mounting surface before application to ensure proper adhesion. Die cutting should be performed with appropriate tooling sized to the target geometry.
