Introduction to RO4003C
Rogers RO4003C is a proprietary woven glass reinforced hydrocarbon/ceramic material that offers the electrical performance of PTFE combined with the manufacturability of epoxy/glass. This material is specifically designed for high-frequency applications, providing low dielectric loss and tight control over dielectric constant (Dk). Unlike traditional microwave laminates, RO4003C does not require special handling or treatments for through-holes, making it a cost-effective solution for RF microwave circuit designs.
Key Features of RO4003C
Dielectric Constant (Dk): 3.38 ± 0.05 at 10 GHz
Dissipation Factor: 0.0027 at 10 GHz
Thermal Conductivity: 0.71 W/m·K
Thermal Coefficient of Dk: +40 ppm/°C (range: -50°C to 150°C)
CTE Matched to Copper: 11 ppm/°C (X-axis), 14 ppm/°C (Y-axis)
Low Z-Axis CTE: 46 ppm/°C
Tg: >280°C
Low Moisture Absorption: 0.06%
