There are many classification methods and varieties of capacitors, according to the material characteristics of capacitors, they can be divided into the following major categories.
1、Aluminium electrolytic capacitor
Capacitor capacity planning for 0.1UF-22000UF, high pulsating current, long life, large capacity of the choice, widely used in power supply filtering, decoupling and other occasions.
2、Film capacitor
Capacitance planning for 0.1PF-10UF, with small tolerance, high capacity stability and very low piezoelectric effect, so it is X, Y safety capacitor, EMI/EMC, X2 safety capacitor.
3、Tantalum capacitor
Capacitance planning 2.2UF-560UF, low equivalent series resistance, low equivalent series inductance. Pulsation absorption, transient response and noise restraint are better than aluminum electrolytic capacitor, which is the ambitious choice for high stability power supply, safety capacitor.

4、Ceramic capacitor
The capacitance is planned to be 0.5PF-100UF, with the crystallization of material and film technology, which is in line with the planning concept of “lighter, thinner and more energy-saving”, ceramic capacitor.
5、Super capacitor
The capacitance is 0.022F-70F, so it is also called “gold capacitor” or “Faraday capacitor” because of its high capacitance. The main features are: super high capacitance, excellent charge/discharge characteristics, suitable for power storage and power backup.
