2. Key Features & Benefits

 

Stable High‑Frequency Performance: Tight dielectric constant control (Dk 3.48 ±0.05 @ 10 GHz) and low dissipation factor (0.0037 @ 10 GHz) ensure consistent signal integrity in RF/microwave bands.

 

Excellent Thermal & Mechanical Stability: High Tg (>280°C), low CTE (X/Y/Z: 10/12/32 ppm/°C), and minimal moisture absorption (0.06%) support reliability in harsh operating environments.

 

Cost‑Effective Microwave Solution: Delivers near‑PTFE performance at a fraction of the cost, with standard FR‑4 processing compatibility and no need for special through‑hole treatments.

 

High Power & Safety Compliance: UL 94 V‑0 rated for flammability, suitable for high‑power RF designs and active component integration.

 

Thermal Management Ready: Thermal conductivity of 0.69 W/m/K assists in heat dissipation for power‑dense applications.
