The measurement conditions used to define an electrolytic capacitor''s capacitance are set forth in IEC standards, ... An ideal capacitor would have R = 0 and a loss coefficient D = 0, but since actual capacitors have various resistance components, including and ...
dielectric dissipation factor due to the polarization losses is: tand P ¼ e00 r e0 r; ð11:4Þ and the dissipation factor due to the conduction losses is: tand L ¼ j xe 0e0 r ð11:5Þ with the specific conductivity j. 11.1.2 Equivalent Circuits for Dielectrics with Losses
Dissipation Factor (DF) is a measure of a capacitor''s losses under AC conditions and is defined as the ratio of ESR (resistive power loss) and reactance (reactive power). Higher DF signifies higher ESR in the capacitor causing self-heating due to I 2 R losses.
Capacitor Parameters: Dissipation Factor (DF), Loss Tangent (tanδ), Equivalent Series Resistance (ESR) and Quality Factor (Q) Capacitor product specifications include multiple parameters which are useful when selecting or comparing capacitors for a given
