Series Connection Formula
Note: In the component parameters, the subscript s represents the series connection equivalent,
and p represents the parallel connection equivalent. In general, the series equivalent circuit shall
be used for low-value impedance elements (basically high-value capacitance and low-value
inductance); on the contrary, the parallel equivalent circuit shall be used for high-value impedance
elements (basically low-value capacitance and high-value inductance). Meanwhile, it is advisable
to determine the equivalent circuit according to the actual use of the components; for example,
when the capacitor is used for power supply filter, the series equivalent circuit shall be used, while,
when the capacitor is used for LC oscillation circuit, the parallel equivalent circuit shall be used.
