Taconic TLX-6 DK 2.65 Df0.0016/0.0022 (0.089-6.35mm) Copper Clad Laminate
Brief Introduction
TLX is a high-volume fiberglass-reinforced microwave substrate offering reliability across a wide range of RF applications. Its versatility stems from a DK range of 2.45–2.65, various available thicknesses, and copper cladding options, making it suitable for low-layer-count microwave designs. TLX PTFE fiberglass laminates are ideal for radar systems, mobile communications, microwave test equipment, transmission devices, and RF components. As a robust substrate for severe environments, its fiberglass reinforcement provides mechanical strength against vibration, high temperatures, radiation, and wide temperature ranges.
