About Rogers RT/duroid 5880LZ Laminate

The RT/duroid 5880LZ laminate is a low-density, ceramic-filled PTFE composite, specifically engineered for stripline and microstrip circuit applications. It offers exceptional electrical properties, lightweight construction, and low dielectric loss, making it the preferred choice for weight-sensitive, high-performance systems.

Key Features of RT/duroid 5880LZ:

• Dielectric Constant (Dk): 2.0 ± 0.04 at 10GHz and 23°C, ensuring stable impedance control.
• Dissipation Factor (Df): Ranges from 0.0021 to 0.0027 at 10GHz, minimizing signal loss.
• Low Z-Axis Coefficient of Thermal Expansion (CTE): 40 ppm/°C, providing outstanding dimensional stability during thermal cycling.
• Low Outgassing Properties: TML 0.01%, CVCM 0.01%, and WVR 0.01%, making it ideal for aerospace and military applications.
• Lightweight Construction: Density of 1.4 gm/cm³ for weight-sensitive designs.
• Flammability: UL 94V-0, ensuring safety compliance.

The RT/duroid 5880LZ laminate is resistant to solvents and reagents, supports lead-free processes, and is easy to machine, shear, and cut.

Benefits of the Laminate and PCB Design
