Real Capacitor Equivalent Circuit. Some of these such as leakage current and parasitic effects are linear or can be analyzed as nearly linear and can be dealt with by adding virtual components to the equivalent circuit of an ideal capacitor. However there are still discrepancies between the two.
However there are still discrepancies between the two. Let s first consider the parallel combination of capacitors as shown on figure 5. A real capacitor can be modeled using a series rlc equivalent circuit.
An rlc circuit is an electrical circuit consisting of a resistor r an inductor l and a capacitor c connected in series or in parallel.
Both losses can be accounted for by the following equivalent circuit diagram for a real capacitor. Note that all capacitors have the same voltage v across them. Here the capacitor c is an ideal capacitor the resistor r is equivalent series resistance and the inductor l is the equivalent series inductance. This particularly applies to emc ferrites with which interference is suppressed but no precise circuitry is formed.
