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).
How Big is the DC Bias Effect in Ceramic Caps?
High DC bias creates an additional problem in ceramic capacitors, where the capacitance of the component is lower when the DC bias is higher.
