3M™ EMI Copper Foil with Acrylic Adhesive Tape 1125

Overview
Data Sheets & Summary Sheets
  • 3M 1125

    3M™ 1125 tape is typically used in a variety of EMI/RFI shielding applications such as shielding small electromagnetic components, repair and modification of printed wiring boards, flat conductor assemblies, prototype designs, supplementary shielding of joints and seams and shielding cable splices.

    This tape has a 1.4-mil smooth copper foil backing coated with a non conductive acrylic pressure-sensitive adhesive. This tape comes linered on a 3-inch paper core for easy die-cutting. Its acrylic adhesive has good resistance to oxidation, solvents and oils. 3M™ EMI Shielding Tape has a multitude of uses in electronic design and test laboratories for prototyping, design and troubleshooting. Tapes with foil backings satisfy many requirements for effective grounding, bonding and EMI shielding. Aluminum, copper backings are available, both smooth and embossed, and with conductive and nonconductive adhesive systems. Both the unique embossed foil tapes and the smooth foil tapes with conductive adhesive offer excellent "through-the-adhesive" conductivity. A copper-plated polyester "rip stop" fabric backing is also available, providing shielding plus strength, flexibility and low weight. Available in custom widths from 1/8 inch to 24 inch, and comes standard on a 18 or 36 yard roll on a 3 inch diameter core..
