EMI absorption tape and sheets filter out broadband noise
The magnetic layer’s powder composite absorbs lower frequency electromagnetic energy, while the conductive layer’s powder and high loss dielectric resin absorb high frequency electromagnetic energy. The products feature a very thin form factor and come in two different tape formats as well as an A4 sheet format, all of which can be easily die-cut to specific configurations.
This dual-layer structure absorbs both the MHz and GHz electromagnetic energy effectively to provide ultra-wideband EMI noise mitigation. The tape and sheets are insulated on one side, so they can be placed in contact with any low-power active component such as noisy digital or analogue integrated circuits.
While Hozox technology converts a portion of the electromagnetic waves it absorbs into heat, the amount is minimal and does not adversely affect temperature rise in the end unit, says the manufacturer.
