Is the capacitance of ceramic capacitors related to voltage?

Ceramic capacitors are a very common capacitor on the market, and the use of ceramic capacitors is increasing as the speed of development. In the subject of this article, we are going to explore whether the capacitance of the ceramic capacitor has a relationship with the voltage.

According to different media, it can be divided into Class I ceramic capacitor and Class II ceramic capacitor. Usually NP0, SL0, COG is Class I ceramic capacitor, X7R, X5R, Y5U, Y5V is Class II ceramic capacitor, Class I ceramic capacitor The capacity stability is very good, basically does not change with changes in temperature, voltage, time, etc., but the general capacity is very small. The capacity stability of Class II ceramic dielectric capacitors is relatively inferior to that of Class I. As temperature, voltage and time vary greatly, it is generally used in applications where capacity stability is not high, such as filtering! Class II ceramic capacitors have a much lower capacity when the DC bias voltage is larger.
