Although the working principle of the chip capacitor is to store and release the charge, it can be divided into two types according to its medium, structure, capacity, use and position.

First, there are polar capacitors mainly using electrolytes as the medium, while non-polar capacitor dielectrics are of various types, mainly using metal oxide films and polyester media.

Secondly, in terms of use and location, the reversible polarity of the capacitive medium and the reversibility of the non-polar medium determine the purpose and position of the two capacitors. For example, to have a filtering effect, only a polar capacitor can be selected.

Finally, in terms of structural shape, the polar capacitance is generally circular, while the shape of the non-polar capacitor is very uniform, and has a tubular shape, a sheet shape, a circular shape, and various combinations of shapes.

In general, the polarity of the chip capacitors is distinctive and easy to distinguish.
