Term:

DC Bias Effect for MLCCs

Definition:

When a DC voltage is applied to class-2 and class-3 multilayer ceramic capacitors(MLCCs), like X7R or Y5V, they lose capactiance. For commerical and automotive grade capacitors, manufacturers typically do not specify this coefficient, or loss.

Military-Grade MLCCs with a two letter designator like BX will have a specified voltage coefficient.

KEMET’s KSIM tool can be used to estimate the DC Bias for a KEMET MLCC.
