About TLY-5 Material
The TLY-5 laminate is a dimensionally stable, low-loss PTFE-based material reinforced with lightweight woven fiberglass. This construction makes it highly suitable for high-frequency and high-volume manufacturing, especially in millimeter-wave frequency applications.
Key Features of TLY-5:
- Dielectric Constant (Dk): 2.2 ± 0.02 at 10GHz/23°C, ensuring precise and consistent impedance control.
- Dissipation Factor (Df): 0.0009 at 10GHz, delivering ultra-low loss for high-frequency signals.
- Density (Specific Gravity): 2.19 g/cm³, providing lightweight construction.
- Moisture Absorption: 0.02%, ensuring stable performance even in humid environments.
- Coefficient of Thermal Expansion (CTE): X-axis: 26 ppm/°C, Y-axis: 15 ppm/°C, Z-axis: 217 ppm/°C
Applications
The TLY-5-based PCB is perfect for a range of high-frequency and RF applications, including:
- Automotive Radar
- Satellite and Cellular Communications
