The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field. Permittivity is a material's property that affects the Coulomb force between two … WebNov 3, 2024 · Author：Kavie. Our commonly used PCB board medium is FR4 material, and the relative dielectric constant of air is 4.2-4.7. This dielectric constant will change with temperature, and the maximum change range can reach 20% in the temperature range of 0-70 degrees. The change of the dielectric constant will cause a 10% change in the line …
