        Its shape is mostly slices, but also tube-shaped, round and other shapes.


         Ceramic capacitor is a general term for capacitors with ceramic materials as the medium. There are many varieties, and the dimensions vary greatly. According to the voltage used, it can be divided into high voltage, medium voltage and low voltage ceramic capacitors. According to the temperature coefficient, the dielectric constant can be divided into negative temperature coefficient, positive temperature coefficient, zero temperature coefficient, high dielectric constant, low dielectric constant, etc. In addition, there are classification methods for Type I, Type II, and Type III. Compared with other capacitors, general ceramic capacitors have the advantages of higher operating temperature, larger specific capacity, better moisture resistance, lower dielectric loss, and the capacitance temperature coefficient can be selected in a wide range. Widely used in electronic circuits, the amount is very considerable.
