| Dissipation Factor (DF) | 0.0019 |
| Moisture Absorption | <0.02% |
| Dielectric Breakdown | >60 kV |
| Volume Resistivity | 10⁷ Mohm/cm |
| Surface Resistivity | 10⁷ Mohm |
| Arc Resistance | >180 seconds |
| Flexural Strength (Lengthwise) | >23,000 lbs./in. |
| Flexural Strength (Crosswise) | >19,000 lbs./in. |
| Peel Strength (1oz copper) | 12 lbs./linear in. |
| Thermal Conductivity | 0.19 W/m/K |
| x-y CTE | 9-12 ppm/°C |
| z CTE | 130-145 ppm/°C |
| UL-94 Flammability Rating | V-0 (flame-retardant) |
5. Core Benefits of TLX-9 PCB
This PCB leverages TLX-9’s inherent advantages to deliver superior
performance:
Low Dielectric Constant (2.5): Minimizes signal loss and crosstalk in high-frequency
applications.
Low Dissipation Factor (0.0019): Ensures efficient power transfer with minimal energy waste.
Near-Zero Moisture Absorption: Prevents performance degradation from environmental humidity.
High Dielectric Breakdown (>60 kV): Supports high-voltage operation without insulation failure.
Strong Peel Strength (12 lbs./linear in.): Enhances bond reliability between copper layers and substrate.
Controlled CTE: Matches thermal expansion of components (x-y CTE: 9-12 ppm/°C),
reducing stress during temperature cycling.
6. Typical Applications
The combination of TLX-9’s properties and the PCB’s precision
construction makes it ideal for:
-Low-Noise Amplifiers (LNAs), Low-Noise Blocks (LNBs), and
Low-Noise Converters (LNCs)
-Personal Communications Service (PCS)/Personal Communications
Network (PCN) systems
-Large Format Antennas
-High Power Amplifiers
-Passive Components (resistors, capacitors, inductors) for
high-frequency circuits
