Introduction to Rogers CLTE-XT
Rogers CLTE-XT laminates are advanced composites designed to enhance loss tangent while delivering the lowest insertion loss and highest dimensional stability in their class. Building on the proven reliability of CLTE laminates, CLTE-XT maintains its properties over an even broader temperature range, making it ideal for high-frequency and temperature-sensitive applications.
Features of CLTE-XT
- Dielectric Constant: 2.79 to 2.94 (varies by thickness) at 10GHz, 23°C @ 50% RH, ensuring consistent signal propagation.
- Dissipation Factor: 0.0010 at 10GHz, 23°C @ 50% RH, minimizing signal loss for high-frequency performance.
- Coefficient of Thermal Expansion (CTE): X axis 12.7 ppm/°C, Y axis 13.7 ppm/°C, Z axis 40.8 ppm/°C, ensuring dimensional stability across temperature fluctuations.
- Decomposition Temperature (Td): 539°C, offering exceptional thermal resistance for harsh environments.
- Thermal Coefficient of Dielectric Constant: -8 ppm/°C, maintaining dielectric stability with temperature changes.
- Dielectric Constant Tolerance: +/- 0.03, the tightest in the CLTE family, ensuring consistent performance across production lots.
- Moisture Absorption: 0.02%, resisting moisture-related degradation for long-term reliability.
