Rogers RO4350B High Frequency Material Parameters

Hits : 5

RO4350B is a patented hydrocarbon resin system/ceramic filler reinforced with woven glass cloth, which has electrical properties very close to those of PTFE/woven glass cloth materials and processability similar to epoxy/glass cloth materials.

RO4350B is able to utilize standard epoxy/glass cloth processing while providing tightly controlled dielectric constants and losses at a fraction of the price of conventional microwave materials. There is no need for special through-hole plating pre-treatment or handling procedures as with PTFE-based microwave materials. It is also UL 94V-0 rated for active equipment and high voltage RF designs.

Rogers Ro4350B HF material.

Dielectric constant: 3.38 ± 0.05;

Loss factor: 0.0027;

Temperature coefficient of dielectric constant: +40;

Volume resistance: 1.7 x 10 & 10;

Surface resistance: 4.2 x 10 & 9;
