Surface Mount Aluminum Electrolytic Capacitors – EEV Series, +105ºC
Frequency Dependence of the Capacitance
Effective capacitance value is derived from the impedance curve, as long as impedance is still in the range where the capacitance
component is dominant.
C=
1 C = Capacitance (F)
2π fZ f = Frequency (Hz)
Z = Impedance (Ω)
Dissipation Factor tan δ (DF)
Dissipation Factor tan δ is the ratio between the active and reactive power for a sinusoidal waveform voltage. It can be thought of as a
measurement of the gap between an actual and ideal capacitor.

Tan δ is measured with the same set-up used for the series capacitance ESC.
tan δ = ω x ESC x ESR where:
ESC = Equivalent Series Capacitance
ESR = Equivalent Series Resistance
Equivalent Series Inductance (ESL)
Self inductance or Equivalent Series Inductance results from the terminal configuration and internal design of the capacitor.
