high frequency absorber sheets 5780-C5G

High frequency absorber sheets 5780-C5G

Works as a high frequency absorber & thermal conduction composite

The material can be used at the same time as a electromagnetic waves absorber and as a thermal conduction material. It is suitable for the medium and low bands (FR1) below 6 GHz (Sub6G) in 5G NR (New Radio) technology because of the high frequency absorbing characteristics.

The 5780-C5G can reduce cavity Resonance Effects caused by high frequency, PCB Edge Radiation, PCB Trace Radiation and Heat-sink Radiation

The product can also be used as a thermal conductive material. Because of it's high thermal conductivity, softness, compressibility and self-adhesiveness it also can be used as a thermal conductive material.

It can be mounted tightly on different surfaces to fill the irregular space between the heat source and the thermal module, so that the high temperature can be effectively transferred from the heat source to the thermal module, thereby achieving the cooling effect.
