Featuring ultra-low electrical resistance (0.003 Ξ©/sq), high tensile strength (36 lbs/in), and heat resistance up to 311Β°F, it’s the go-to solution for professional-grade electronics repair, prototype design, and static charge management. ## Description JVCC CFL-5CA Copper Foil Tape is a 1 ounce 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. Country of Origin: Italy. Warning: This product can expose you to chemicals including Toluene, which is [are] known to the State of California to cause birth defects or other reproductive harm.

The description says that it's 3.5 mils (.0035") thick, and of course it's 0.25" wide. That defines the cross-sectional area of the tape. The resistivity of copper is 16.78*10^-9 ohm-meters. Converting the inch measurements to metric and plugging into the standard formula, I get that the tape has a resistance of about 0.00075 ohms per linear inch, or 0.75 milliohms per linear inch.What this means is that for each inch of tape, you add an incremental resistance of .00075 ohms. If you roll out 10 feet of the stuff (120"), the end-to-end resistance will be 0.09 ohms. If you run 1 amp through this tape length of 120", you will see a voltage drop of about .09 volts. (Voltage drop equal current times resistance, which is called "Ohm's Law" in the business.) Bear in mind that this is just for one of the conductors. If you use this tape for a 2-wire power system, the other piece of tape will experience the same current drain, so it, too, will have a .09 volt drop across it. This results in a total voltage drop at the end of 2*.09V = .18V.You can easily calculate the resistance of other tape widths by decreasing the .00075 ohm figure by the ratio of the other tape width divided by this tape width of 0.25". For instance, 1" tape is 1.0"/0.25" = 4, so decrease the resistance by a factor of 4, resulting in .00019 ohms. Wider tape means less resistance, and therefore less voltage drop per length of the tape. ### ⭐⭐ Poor conductor of electricity *by T***P on December 11, 2012* The only reason I purchased product is due expected properties of conductivity. Tape was poor and messy better of and easier using soider to tab solar cells. ### ⭐ The adhesive does not conduct electricity *by V***H on June 22, 2013* Since heating batteries can damage them, I wanted to avoid solder to create new battery packs for our phones. Instead, I attempted to use the JVCC CFL-5CA Copper Foil Tape with Conductive Adhesive (1/4 in. x 36 yds). However, the adhesive is not conductive at all. To test this, I securely wrapped the ends of my multimeter probes with a section of the tape. With the adhesive side in contact with the probe surfaces, I measured an open circuit. Given that the reason to pay a premium for this expensive tape is the promise of conductive adhesive, this warrants a rating of one star. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/956236-jvcc-copper-foil-tape-conductive-adhesive-cfl-5ca-1-4](https://www.desertcart.tn/products/956236-jvcc-copper-foil-tape-conductive-adhesive-cfl-5ca-1-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
