What is a high-volume high-voltage patch capacitor

Generally speaking, the larger the volume, the larger the capacitance that can be achieved, called high volume patch capacitor, conversely, the smaller the size of the patch capacitor, the smaller the capacitance can be achieved, it is called low volume patch capacitor.

The high voltage patch capacitor corresponds to the voltage, generally voltage above 100V is called high voltage patch capacitor, commonly used 100V, 200V, 250V, 500V, 630V, 1KV and so on. The size of the volume determines the high pressure and the error range.
