FAQ
Does the capacitance of ceramic capacitors change by voltage?

The low internal resistance of ceramic capacitors is very helpful for low output ripple and can suppress high-frequency noise, but the capacitance of ceramic capacitors attenuates at high voltage. Why?

The attenuation of ceramic capacitor capacitance at high voltage is related to the properties of the material used in the ceramic capacitor.

The material used in the ceramic capacitor is a ceramic with a high dielectric constant, the main component is barium titanate, and its relative dielectric constant is about 5000, and the dielectric constant is relatively high. What does a high dielectric constant mean? Materials with high dielectric constants can store more energy compared to those with low dielectric constants.

Since the dielectric can reduce the strength of the electric field, it is not easy to be broken down, so the ability of the capacitor to store electric charge can be improved, that is, the capacitance is improved. However, under high voltage, the electric field strength in the dielectric will continue to increase, and the dielectric constant will gradually decrease, which is why the capacitance of ceramic capacitors decays under high voltage.
