Overview of This Type of Laminate
RT/duroid 5880 is a glass microfiber reinforced PTFE composite designed for high-performance stripline and microstrip printed circuit board applications. With a dielectric constant of 2.20 and ultra-low dissipation factor, it provides exceptional electrical consistency and signal integrity, making it suitable for demanding RF and microwave systems up to Ku-band and beyond.
Technical Features & Benefits
Low and Stable Dielectric Constant: Dk = 2.20 ±0.02 at 10 GHz, with excellent uniformity across panels and frequency stability.
Ultra-Low Loss: Dissipation factor as low as 0.0009 at 10 GHz, supporting high-frequency, low-loss designs.
Excellent Thermal Stability: Thermal coefficient of εr = -125 ppm/°C, ensuring reliable performance across temperature ranges.
High Electrical Insulation: Volume resistivity ≥2×107 MΩ·cm and surface resistivity ≥3×107 MΩ.
Good Mechanical Properties: Balanced tensile and compressive modulus for reliable PCB fabrication and assembly.
