- Dielectric Constant: 2.2 with a tight tolerance of ±0.02 at 10 GHz/23°C
- Dissipation Factor: 0.0009 at 10 GHz
- Temperature Coefficient of Dielectric Constant (TCDk): -125 ppm/°C
- Moisture Absorption: Low at 0.02%
- CTE (Coefficient of Thermal Expansion):
- X-axis: 31 ppm/°C
- Y-axis: 48 ppm/°C
- Z-axis: 237 ppm/°C
- Isotropic Properties: Ensures consistent performance in all directions
