Understanding Capacitor Types and Characteristics | DigiKey
AC voltages cause the polarization of the dielectric to change on every cycle, causing internal heating. The dielectric heating is a function of the material and is measured as the dissipation factor of the dielectric. The dissipation factor (DF) is a function of the capacitor''s capacitance and ESR, and can be calculated using Equation 2:

In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effec…
