WebFeb 19, 2005 · Yes it's correct that tan δ = σ/ωε. Loss tangent is the ration b/w the imaginary and real parts of the complex permittivity. where the complex permittivity can be defined as εc = ε-j (σ/ω) The valie of the loss tangent describes how lossy a material is, if σ » ω ε, it represents a very lossy material or a very good conductor. A capacitor is a discrete electrical circuit component typically made of a dielectric placed between conductors. The lumped element model of a capacitor includes a lossless ideal capacitor in series with a resistor termed the equivalent series resistance (ESR), as shown in the figure below. The ESR represents losses in the capacitor. In a low-loss capacitor the ESR is very small (the conduction is …
