There are three families of electrolytic capacitor: aluminium electrolytic capacitors, tantalum electrolytic capacitors, and niobium electrolytic capacitors. The large capacitance of electrolytic capacitors makes them particularly suitable for passing or bypassing low-frequency signals, and for storing large amounts of energy.
The characteristics of the capacitors are clearly divided into two areas. At low frequencies (fl), capacitors behave mainly capacitively and their imaginary parts can be likened to − 1 Cω reactance. However, with increasing frequency, the inductive effect grows on the rest of the parameters until it dominates the behavior of these components.
The lifetime, service life, load life or useful life of electrolytic capacitors is a special characteristic of non-solid aluminium electrolytic capacitors, whose liquid electrolyte can evaporate over time. Lowering the electrolyte level affects the electrical parameters of the capacitors.
However, solid polymer electrolytic capacitors, and aluminium, tantalum, and niobium electrolytic capacitors also have a lifetime specification. The polymer electrolyte exhibits a small deterioration of conductivity caused by thermal degradation of the conductive polymer.
The size of an electrolytic capacitor is determined by its physical dimensions and the characteristics of the insulating medium between the two plates. Inside the capacitor is an electrolyte material that stores electric charge and has positive and negative polarity.
An electrolytic capacitor contains an electrolyte material that stores electric charge. It has positive and negative polarity, similar to a battery, and cannot be reversed. The positive electrode is a metal substrate with an oxide film inside the capacitor.
The dielectric thickness of electrolytic capacitors is very small, in the range of nanometers per volt. On the other hand, the voltage strengths of these oxide layers are quite high. With this very thin dielectric oxide layer combined with a sufficiently high dielectric strength the electrolytic capacitors can achieve a high volumetric capacitance.
