Q.ESR characteristics (3): How much difference is there in ESR between different value MLCCs (Multilayer Ceramic Chip Capacitors)?

A. When comparing different dielectric material, generally speaking, Class I dielectrics yield lower ESR compared to Class II dielectrics with all other variables being the same. Class I dielectrics, however have lower dielectric constants and therefore cannot offer the high capacitance values you can achieve with class II dielectrics.
High value ceramic capacitors typically have a high internal electrode layer count. If you consider each layer of the MLCC as a resistor, the circuit model for the inner electrodes is equivalent to several resistors in parallel. Since resistors in parallel reduce in value, it follows that higher layer count MLCCs result in lower ESR. This, of course, is assuming all other parameters are equal.
