What is a ceramic capacitor, and what are the differences between a ceramic capacitor and an electrolytic capacitor?

(2) Low frequency ceramic capacitor: It is a type of capacitor that combines a ceramic substrate and metal electrodes. It has the characteristics of large capacity, high accuracy, and low temperature coefficient, and is mainly used in low-frequency circuits. diode

(3) High voltage ceramic capacitor: It is a type of capacitor that combines a ceramic substrate and metal electrodes, and has the characteristics of high voltage resistance and high temperature resistance. It is mainly used in high-voltage circuits.

2、 The working principle of ceramic capacitors

Ceramic capacitor is a type of capacitor that works on the same principle as other capacitors. A capacitor is an electronic component that stores electric charge, consisting of two conductor plates separated by an insulating material. When a voltage is applied across the capacitor, charge accumulates between the two conductor plates and forms an electric field. The capacity of a capacitor depends on the distance between two conductor plates and the dielectric constant of the insulation material.

Ceramic capacitor is a type of capacitor that combines a ceramic substrate and metal electrodes. Ceramic matrix is an insulating material, while metal electrode is a conductor plate that forms an electric field. When an external electric field acts on a ceramic capacitor, charges between the metal electrodes accumulate and form an electric field. The capacity of a capacitor depends on the dielectric constant of the ceramic substrate, the distance between the metal electrodes, and the area of the metal electrodes.  diode
