3M Tin Plated Copper Foil EMI Shielding Tape 1183 is a 2.6 mil thick, acrylic adhesive shielding tape. This flame retardant tape is suitable for applications that require outstanding electrical conductivity from the application substrate through the adhesive to the backing. It comes on a removable liner for easy die cutting and handling. The tape is rated for 600V dry applications.3M EMI Shielding Tape 1183 has a deadsoft, copper foil backing with a pressure sensitive, electrically conductive, acrylic adhesive that ensures firm adherence. This tape has tin plating, which resists oxidation and facilitates soldering to the backing. The conductive particles in the adhesive offer low resistance between the substrate and the backing. This tape withstands a wide temperature range of 40 to 266 °F ( 40 to 130 °C). This flame retardant tape is designed for grounding and EMI shielding in equipment, components and shielded rooms. UL Listed and RoHS 2011/65/EU Compliant.
