and die-cuttingLike all shielding tapes, CN 3190 tapesare available in
standard and custom widths andlengths. Standard length is 25M.b l; Widths
from 6mm to 1050mmb l; Longer lengths up to several times normallength,
dependent upon width. Check withCustomer Service.Applications CN 3190
Cu/Ni fabric tape is typically used inmany applications typically served by metal foilshielding tapes such as grounding and EMIshielding in equipment, components, shieldedrooms, etc.The unique metalized fabric backing offers theadditional
benefits of excellent flexibility andconformability, very light weight, and exceptionalstrength. The fabric backing also minimizes thepossibility of finger lacerations.Shielding EffectivenessMany factors determine the true shieldingeffe
ctiveness of a shielding tape, including typeand thickness of foil, adhesive type,
intimacy ofcontact, smoothness of application surface,strength and frequency of
the EMI signal, etc.However, using standard tests and fixtures, it ispossible to
determine a value for the attenuation.For CN 3190 Cu/Ni fabric tape, typical
shielding effectiveness is in the range of 65dB to70dBCN 3190 Cu/Ni Fabric Tape –
