What Makes TFA615 Unique?
About TFA Series
TFA series substrates are polytetrafluoroethylene (PTFE) ceramic composites, crafted without traditional glass fiber cloth. Instead, they use a new prefabrication process and special lamination, resulting in aerospace-grade performance that rivals foreign alternatives. Key traits:
-No glass fiber cloth, eliminating "fiberglass effect" in electromagnetic wave propagation
-Uniform nano-ceramic mix for stable frequency performance and minimal dielectric loss
-Low anisotropy (X/Y/Z) and copper-matched thermal expansion
-Stable dielectric temperature characteristics
-Four dielectric constant options: 2.94 (TFA294), 3.0 (TFA300), 6.15 (TFA615), 10.2 (TFA1020)
TFA615 Features
-Dielectric constant (Dk): 6.15±0.12 at 10GHz
-Dissipation factor: 0.0015 at 10GHz; 0.0017 at 20GHz
-CTE (–55°C to 288°C): X=16 ppm/°C, Y=16 ppm/°C, Z=29 ppm/°C
-Thermal conductivity: 0.8 W/mk
-Moisture absorption: 0.06%
-UL 94-V0 rating
-Td (decomposition temperature): 503℃
Ideal Applications
-Aerospace equipment, spacecraft, and in-cabin systems
-Microwave components and antennas (including phase-sensitive types)
