polymer_dielectric_constant_254

This is a polymer-based dielectric material identified by its dielectric constant value of 2.54, placing it in the lower-loss dielectric family suitable for high-frequency electrical applications. Polymers in this dielectric range are commonly used in RF/microwave substrates, printed circuit boards, and capacitive components where low signal loss and stable permittivity are critical. The material would be selected over ceramics when flexibility, machinability, or lower cost is needed, and over standard epoxy resins when tighter dielectric control and frequency stability are required.
