What is the capacitance of the ceramic capacitor?

The main material of the ceramic capacitor is ceramic tile. The ceramic tile is sintered by high temperature after the ceramic powder is pressed and pressed. The appearance will not change with time, so the storage period is long-lasting. However, most of the ceramic capacitors used in the class 2 are ceramic materials with ferroelectric properties and exhibit a Curie temperature characteristic. Therefore, the ceramic capacitor has an aging decay phenomenon.

Often entangled in this small problem, the capacitance is determined by the impedance exhibited when measuring the AC capacity. Usually the AC capacity varies with frequency, voltage and measurement method, except that ceramic capacitors of different specifications vary in degree. However, the temperature characteristics are particularly stable unless the capacitance is required to be particularly accurate.

Although the capacitance of ceramic capacitors varies under different conditions (such as frequency, temperature, voltage), in addition to high dielectric ceramic capacitors, the capacitance of general capacitors is lower than the capacitance depending on the application conditions. Tolerance. Capacitance is an important electrical parameter of a capacitor, the size of the capacitance, the tolerance of the capacitance, and stability over time, when you understand the capacitance. As long as you find the rules of the product, you will find a different miracle.
