Rogers RT/duroid 6202PR DK2.94 Df0.0015 (0.005-0.030") PTFE Ceramic Laminate with Resistive Foil
Brief Introduction
RT/duroid 6202PR is a PTFE/ceramic laminate designed for high-frequency circuit applications requiring embedded resistive elements. It offers a dielectric constant of 2.94 ±0.04 (for thicknesses ≥0.020") and a dissipation factor of 0.0015 at 10 GHz. The material provides excellent thermal stability with a thermal coefficient of dielectric constant of +5 ppm/°C, making it ideal for applications requiring consistent electrical performance across a wide temperature range. The "PR" designation indicates the inclusion of resistive foil for embedded resistor applications.
