Dielectric loss tangent or dissipation factor (Tan δ or Df) A material’s loss tangent gives a measure of the power lost due to the material. The lower a material’s loss tangent, the less power is lost. The Tan δ of most PCB materials ranges from 0.02 for most commonly used material...

where ε′ retains its significance as the relative permittivity (dielectric constant), and ε″ is commonly regarded as the dielectric material's loss factor (dielectric loss). At this point in the discussion, some of the general features of a real dielectric material can be considered in the...
Fig. 2. In the left panel we show the log of the loss function Im[−1/ϵ(ω, q)] for the extended Drude dielectric function with ωp = 15 eV and as a solid red line the Bethe dispersion. The dotted line is the energy transfer to a stationary electron (q2/2) and the white...
The dielectric may have a dielectric constant (Dk) of greater than or equal to about 3900 or more and dielectric loss (Df) of less than or equal to about 0.2 at a frequency of about 10 kHz. The dielectric paste may be applied to a substrate by processes that include tape coating, scre...
A dielectric ceramic composition has a dielectric constant, K, of at least 200 and a dielectric loss, DF, of 0.0006 or less at 1 MHz. The dielectric ceramic composition may be forme
The dielectric loss tangent increases with increasing pressure and rapidly near the transition pressure, and decreases with increasing dc electric field. These experimental results are explained by means of a phenomenological theory.doi:10.1080/00150199208218001...
