By converting capacitance to impedance, engineers and designers can accurately predict the behavior of capacitors in AC circuits, enabling them to make informed design decisions. Impedance also plays a critical role in impedance matching, a technique used to ensure maximum power transfer between components in a circuit.
The size of the impedance is related to the capacitance and the frequency of the AC. Unlike resistance, impedance does not consume electrical energy and convert it into heat energy, but stores and releases electrical energy in the capacitor. Figure 2: Impedance of capacitor
On the other hand, a capacitor with smaller capacitance generally has a smaller size, leading to a lower ESL. Therefore, its self-resonance frequency is high and a low impedance is obtained in the high frequency region. However, due to the small capacitance value, the impedance increases in the low frequency region.
Capacitance and capacitor impedance are two very important concepts in electronics and electrical engineering. Capacitance is a measure of a capacitor's ability to store charge. It is measured in Farads (F), defined as the number of Coulombs (C) stored per Volt (V). A capacitor with a high capacitance can store more charge at the same voltage.
The process of converting capacitance to impedance There are capacitive reactance calculators that allow you to determine the impedance of a capacitor as long as you have the capacitance value (C) of the capacitor and the frequency of the signal passing through the capacitor (f).
The impedance of a capacitor, Zcap, can be calculated using the equation Lbl = Zcap / (2 * π * f). The actual inductance (Lbl) can be determined from the rising part of the impedance curve.
Although capacitance in an AC circuit is easily discernible, the parameter impedance in an AC circuit requires thorough circuit analysis. Keeping this in mind, obtaining a greater understanding of the relationship between capacitance and impedance is paramount.

On a 30 mil-board adding the capacitors at a close distance had a large impact (Figure 7); moving them 1.5 inch away had a similar large impact (Figure 9), but moving them 2 inches away (Figures 11 and 12) had no impact on the board impedance. That is, placing the capacitors too far (2 inches) renders them useless as they provide no benefit!

Impedance is the overall opposition to the flow of alternating current (AC) and is a combination of reactance and resistance. The impedance of a capacitor is given by the equation Z C = √(R C 2 + X C 2), where R C is the resistance. The impedance of a capacitor decreases as the frequency increases, making it more conductive to AC signals.
