Dual-Layer Materials Suppress EMI Noise

Feb. 25, 2014
These tapes and sheets provide EMI suppression from RF through microwave frequencies for noise suppression in a variety of industries.

The HOZOX Electromagnetic Interference (EMI) Absorption Tape and Sheets provide a flexible means for controlling EMI radiation noise in a wide range of electronic products, from consumer through medical and commercial goods. These EMI-absorbing materials employ a unique dual-layer design to optimum EMI noise suppression. A magnetic layer absorbs lower-frequency EM energy while a conductive layer with dielectric resin addresses higher-frequency EM energy. The materials boast a thin form factor and are available in two different tape formats as well as an A4 sheet format, which can be easily die-cut to specific configurations. The absorption tape and sheets are insulated on one side for ease of placement in different circuits. The lead-free materials are RoHS-compliant and meet UL 94V-0 requirements for flammability.
