JVCC CFL-5CA Copper Foil Tape is a 1 oz. rolled copper foil which provides excellent solderability and conformity. Used for RFI/EMI (electromagnetic interference/radio-frequency interference) shielding applications in the electrical/electronics industry (used to shield integrated circuit chips, cables and motors). CFL-5CA is coated with an acrylic adhesive which is uniformly dispersed with conductive spheres. Its conductive adhesive is ideal for printed circuit board modification, security-alarm circuit repairs, and prototype wiring-board layout and design. Also for cable wrapping to provide EMI/RFI shielding, seaming of EMI/RFI shielded rooms for electrical continuity, static charge draining and for surface contact to non-solderable materials (e.g. aluminum or plastics). The copper foil sheet resistivity is 0.003 Ohms/square inch. Its aggressive acrylic adhesive system creates a superior bond. Annealed and non-tarnishing, bright copper color. Flammability: File #130121, UL 510, Section 4. Can also be used for decorative arts & crafts projects. If not otherwise specified widths shown in dropdown are in inches. NOTES: Sizes shipped will typically be the tape industry standard metric-cut sizes, i.e. 24mm for each 1 inch of nominal tape width ordered (rolls are approximately 5% narrower than the nominal size). This product's actual size is 6.3mm wide. This tape is typically cut to width from log rolls so most sizes ship on a plain white core.
