Relationship between conductor and capacitor loss

Dielectric loss

OverviewDiscrete circuit perspectiveElectromagnetic field perspectiveExternal links

A capacitor is a discrete electrical circuit component typically made of a dielectric placed between conductors. One 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 …
