RT/duroid 5880 Material Overview
RT/duroid 5880 is a high-performance glass microfiber reinforced
PTFE composite designed for high-precision microstrip and stripline
circuit applications. Its random microfiber structure delivers
excellent dielectric constant uniformity throughout the substrate.
The material maintains stable dielectric performance across a broad
frequency range with an ultra-low dissipation factor, enabling
consistent low-loss signal transmission for Ku-band and higher
millimeter-wave frequency applications.
Core Material Features & Functional Benefits
Ultra-Low Electrical Loss: Delivers minimal signal attenuation
among reinforced PTFE substrates, enabling high-fidelity signal
transmission for millimeter-wave and high-frequency RF circuits.
Excellent Frequency Stability: Maintains a stable DK of 2.2 ± 0.02
and ultra-low DF of 0.0004–0.0009 at 10GHz, ensuring consistent
electrical performance for broadband designs across wide frequency
bands.
Low Moisture Absorption: With a low moisture absorption rate of
0.02%, it resists humidity interference and sustains stable
dielectric properties in diverse working environments.
Isotropic & Uniform Structure: The all-direction uniform structure
supports precise impedance control, ensuring stable performance and
high repeatability for mass production.
Superior Chemical Resistance: Tolerates various industrial
chemicals and cleaning solutions during processing, protecting
circuit integrity and boosting production yield and long-term
reliability.
Safe & Process-Friendly: Features UL 94V-0 flame retardancy and
full lead-free process compatibility, conforming to modern
industrial safety and manufacturing specifications.
