Equivalent Series Resistance (ESR)
Equivalent series resistance is the resistive component of the equivalent series circuit. ESR value depends on frequency and
temperature,andisrelatedtothetanδbythefollowingequation:
ESR=Equivalentseriesresistance(Ω)
ESR =

ESC = Equivalent series capacitance (F)
f = Frequency (Hz)
Tolerance limits of the rated capacitance must be taken into account when calculating this value.
