What Makes RT/duroid 5880 the Ideal Choice for High-Frequency PCBs?

Overview 

RT/duroid 5880 laminates are composite materials made by combining PTFE with randomly distributed glass fibers, celebrated for their exceptional performance characteristics. They are specially designed to meet the needs of applications requiring high-frequency operation and broadband functionality. With a low dielectric constant (Dk) and minimal dielectric loss, these laminates excel in enabling stable and accurate signal transmission. Thanks to the randomly oriented microfibers that strengthen the PTFE composites, Rogers  5880 maintains consistent dielectric constant uniformity.  

Key Features 

• RT duroid 5880 boasts a dielectric constant (Dk) of 2.20 +/- 0.02, guaranteeing steady signal travel. At 10GHz, its dissipation factor is as low as 0.0009, which reduces energy loss during transmission and preserves strong signal integrity.  

• This duroid 5880 material has an extremely low moisture absorption rate of just 0.02%, making it highly suitable for high-humidity settings. Even in such environments, it keeps its electrical and mechanical properties intact.  

• Rogers duroid 5880 displays isotropic properties, meaning signals propagate uniformly in all directions—perfect for applications that require multi-directional signal transmission.  

• Beyond its electrical advantages, Rogers RT5880 laminates are easy to process, allowing for efficient cutting, shaping, and machining. They also resist solvents and reagents used in etching or plating processes, ensuring long-lasting performance in harsh chemical conditions.  

• As a well-proven material, RT/duroid 5880 stands out among reinforced PTFE materials with the lowest electrical loss, further enhancing signal integrity.
