SRF001 Ceramic Powder Filled PTFE Substrate

SRF001 Ceramic powder filled PTFE substrate is applied to the design of precise stripline and microstrip line circuits. Its unique filler makes the material have the characteristics of low density and lightweight, which can meet the requirements of high-frequency performance and weight sensitive applications. The substrate material has the lowest dielectric constant and small fluctuation in the wide frequency range. The low loss factor can expand its application to Ku and above frequency bands.
