High-Performance IT-180A Material Benefits

With high thermal reliability, it withstands extended exposure to elevated temperatures, achieving T288 >20 minutes and T266 >60 minutes, ensuring stability during lead-free reflow and harsh operating conditions.

The material's low coefficient of thermal expansion (CTE)—11-15 ppm/°C in the X/Y axes—minimizes warpage and enhances dimensional stability, critical for multilayer PCBs in high-temperature environments.

For high-speed designs, IT-180A provides excellent signal integrity, featuring a dielectric constant (Dk) of 4.4 and dissipation factor (Df) of 0.015 at 10GHz, reducing signal loss and maintaining consistent performance in RF and high-frequency applications.

Additionally, the material offers superior anti-CAF (conductive anodic filament) resistance, preventing electrical failures and ensuring high through-hole reliability in humid or high-voltage conditions.

Compliant with modern environmental standards, IT-180A is lead-free and UL 94 V0 flame-retardant, meeting stringent safety requirements for automotive, industrial, and telecommunications applications.
