Figure 1 shows an example of dc bias on capacitance for a 22 uf 35 v 1210 capacitor 35 v is the highest voltage 22 uf capacitor available in the 1210 case size.

Ceramic capacitor voltage bias.

The capacitance is also dependent on the ac bias level. The mechanism of dc bias characteristic in the high dielectric constant capacitor type of ceramic capacitors at present mainly batio3 barium titanate is used as a principal component of high dielectric. Note that the 0 5mm tall x5r component possibly due to having thinner dielectric layers has substantially more capacitance loss for the same bias voltage. I would have expected that using a 25v rated capacitor at 12v would have less variation than a 16v rated capacitor under the same bias.

At 25 v it has lost about 80 percent of its rated capacitance so the actual capacitance is about 4 4 uf. Figure 1 shows the relationship between the rate of change in capacitance and a range of dc bias voltages for 22 µf ceramic capacitors of different sizes with voltage rating of 6 3 v. Ceramic capacitors characteristics faq no 0005. Advances in mlccs multilayer ceramic chip capacitors have allowed manufacturers to achieve very high nominal capacitances.

A second interesting point is that within a package size and ceramic type the voltage rating of the capacitors seems often to have no effect. Also found as maxim integrated application note 5527 temperature and voltage variation of ceramic capacitors or why your 4 7µf capacitor becomes a 0 33µf capacitor by mark fortunato. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications. This video details the dc bias effect on class two mlccs.

However they still suffer from from some drawbacks including a loss of capacitance with increased bias voltage. This will only be linear when using a capacitor with constant capacitance up to 5v bias voltage mks mkt etc. As the applied dc voltage increases the ceramic capacitor s effective capacitance decreases. Figure 14 shows the dc bias dependence of capacitance for these three parts predicted by the vendor s data base.
