Customer ServiceAbove 10MHz, the impedance of the capacitor starts to increase because the impedance is now determnied by the equivalent series inductance. The ideal capacitor would have an infinitely decreasing impedance. When designing circuits in the high frequency range, the impedance curve of your actual capacitor needs to be considerated to avoid any issues. Also, it is important to

Customer ServiceLooking at Figure 9, we know that the series impedance XS2 (whether a capacitor or inductor) translates the series 2.1 Ω load resistor to a larger equivalent parallel resistance, plus some arbitrary parallel reactance. Therefore, we can choose XP2 to be equal but opposite to this arbitrary parallel reactance and create an open circuit. We are then left with
Customer ServiceCapacitors, or caps, store energy in an electric field between their plates. The impedance of a capacitor, known as capacitive reactance (XC), decreases with an increase in frequency. The formula for capacitive reactance is XC = 1/(2πfC), where C is the capacitance. Capacitors oppose changes in voltage, which gives them a unique role in AC

Customer ServiceVery briefly, ESR is a measure of the total lossiness of a capacitor. It is larger than Ras because the actual series resistance is only one source of the total loss (usually a small part). At one frequency, a measurement of complex impedance gives two numbers, the real part and the imaginary part: Z = Rs + jXs.
Customer ServiceAt any specific frequency, an impedance may be represented by either a series or a parallel combination of an ideal resistive element and an ideal reactive element, which is either capacitive or inductive (as illustrated in Figure 1). Such a representation is called an equivalent circuit.

Customer ServiceDischarging. Discharging a capacitor through a resistor proceeds in a similar fashion, as illustrates. Initially, the current is I 0 =V 0 /R, driven by the initial voltage V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V.
Customer ServiceThe total capacitance ( C T ) of the series connected capacitors is always less than the value of the smallest capacitor in the series connection. If two capacitors of 10 µF and 5 µF are connected in the series, then the value of total capacitance will be less than 5 µF. The connection circuit is shown in the following figure.
In order to represent this fact using complex numbers, the following equation is used for the capacitor impedance: where ZC is the impedance of a capacitor, ω is the angular frequency (given by ω = 2πf, where f is the frequency of the signal), and C is the capacitance of the capacitor. Several facts are obvious from this formula alone:
The resistance of an ideal capacitor is infinite. The reactance of an ideal capacitor, and therefore its impedance, is negative for all frequency and capacitance values. The effective impedance (absolute value) of a capacitor is dependent on the frequency, and for ideal capacitors always decreases with frequency.
From formula (1), the amount of impedance |Z| decreases inversely with the frequency, as shown in Figure 2. In an ideal capacitor, there is no loss and the equivalent series resistance (ESR) is zero. Figure 2. Frequency characteristics of an ideal capacitor
If two capacitors of 10 µF and 5 µF are connected in the series, then the value of total capacitance will be less than 5 µF. The connection circuit is shown in the following figure. To get an idea about the equivalent capacitance, Let us now derive the expression of the equivalent capacitance of two capacitors.
When n numbers of capacitors are connected in series, then their equivalent capacitance is given by, From these two expressions, it is clear that the mathematical expression of equivalent capacitance of capacitors in series is in the same form as the expression of resistance in parallel.
