In electronic circuits, high-voltage capacitors are used to block DC and to store and release charges to act as filters to smooth out pulsating signals. A small capacitance, usually used in high-frequency circuits, such as radios, transmitters, and oscillators. Large capacity capacitors are often used for filtering and storing charges. And there is a feature, usually more than 1 μ F capacitors are electrolytic capacitors, and less than 1 μ F capacitors are mostly ceramic capacitors.
Of course, there are other, such as monolithic capacitors, polyester capacitors, small capacity of mica capacitors and so on. The electrolytic capacitor has an aluminum shell filled with electrolytes and leads to two electrodes, which, unlike other capacitors, have no polarity in the circuit, but no polarity in the other capacitors.
