6 FAQs about [Comparison of capacitor impedance curves]

What are the frequency characteristics of capacitor impedance?

In the capacitive characteristic region, the larger the capacitance, the lower is the impedance. Moreover, the smaller the capacitance, the higher is the resonance frequency, and the lower is the impedance in the inductive characteristic region. Our explanation of the frequency characteristics of capacitor impedance may be summarized as follows.

What are the characteristics of a capacitor?

1. Frequency characteristics of capacitors The impedance Z of an ideal capacitor (Fig. 1) is shown by formula (1), where ω is the angular frequency and C is the electrostatic capacitance of the capacitor.

What is the difference between a capacitor and an inductor?

At DC (ω = 0), capacitors have infinite impedance and can be replaced by open circuits, while inductors have zero impedance and can be replaced by wires. As the frequency increases, inductors have increasing impedance, while capacitor impedances decrease.

How is impedance calculated in a capacitor?

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.

What is the difference between capacitance and impedance?

and the impedance in the high-frequency region is lower. The larger the capacitance, the lower is the impedance in the capacitive region. The smaller the ESR, the lower is the impedance at the resonance frequency. The smaller the ESL, the lower is the impedance in the inductive region.

How many comers does a capacitor have?

A capacitor has two impedance components, represented by Zb1 and Zb2 in the figure. At lower frequencies, the impedance provided by Zb1 (associated with capacitance Cb1) is the lower impedance. However, at higher frequencies, Zb1 starts resonating and its impedance begins to rise at fRbl.
