WebThe dielectric permittivity of a material is a complex number containing both real and imaginary components and is dependent on frequency, temperature, and the properties of the material. This can be expressed by: [1] r is the real dielectric permittivity, ε i is the imaginary dielectric permittivity and (Topp 1980). WebThe dielectric constant (Er) or relative permittivity (Dk) of a PCB material is generally between 3.5 and 5.5. A material’s Er level depends on frequency and will usually drop as the frequency rises. The Dk level changes less on certain PCB materials than on others.
