Another design consideration is capacitance shift on Class 2 and 3 dielectrics when voltage is applied. This is called Voltage Coefficient of Capacitance or V_CC. This slide shows an example of V_CC measured on a Class 2 X7R and Class 1 C0G MLCC from 0 V_DC to 16 V_DC on a 16 V rated part. On the left, the graph shows a shift in capacitance up to -60% at rated voltage. Notice that the graph on the right shows 0 capacitance shift for Class 1 C0G over the entire voltage range. This is another reason why Class 1 MLCCs are ideal for applications such as resonant converters and wireless power transfer circuits.
