ESR of capacitor and e-capacitor
As the frequency rises, ESR resulting from parasitic inductance, electrode resistivity and other factors causes |Z| behavior to stray from that of an ideal capacitor (red broken line) and reach a minimum value. The frequency at which |Z| is the minimum value is called the self-resonant frequ...
It can be seen from formula (1) that the impedance | Z | decreases in inverse proportion to frequency as shown in figure 2. Because there is no loss in the ideal capacitor, the equivalent series resistance (ESR) is zero. Cap_20130214_eng4_bw.png Figure 2. Frequency characteristics of i...
It should be noted that this principle of measuring ESR is not new, it is simply not very common. The capacitance is calculated by measuring the charging time of the capacitor between 30mV and 60mV with the same constant current of 10mA. In practice, the "33" gain output is used to ...

Capacitance is a measure of the energy storage ability of a tantalum capacitor, given as C = K A/D, where A is the area of the electrodes, D is their separation, and K is a function of the dielectric between the electrodes. The formula yields a result in farads (F), but a farad...
