How to Measure Capacity Versus Bias Voltage on MLCCs
High-capacity, multilayer ceramic capacitors (MLCC) have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon is present in all high-dielectric constant, or Class II capacitors (B/X5R R/X7R, and F/Y5V characteristic).

Capacitor in Electronics
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …

The Fundamentals of Capacitors in AC Circuits
Without resistance in the circuit, the capacitance charges according to the rate of change of the applied voltage. That means that when the voltage changes the most, the current in the capacitor will be the greatest. When the voltage reaches its maximum value, the current will be zero, but as the voltage decreases, the current changes direction.

At 0 o the rate of change of the supply voltage is increasing in a positive direction resulting in a maximum charging current at that instant in time. As the applied voltage reaches its maximum peak value at 90 o for a very brief instant in time the supply voltage is neither increasing or decreasing so there is no current flowing through the circuit.
