Recommendation for each MLCC size:
01005: for circuits with exceedingly limited space.
0201: recommended for general series,cover capacitance from 0.1pF to 2.2μF. 0201 has the largest supplying capacity.
0402: acceptable but not recommended as most industries have shifted to smaller size and so do the suppliers.
0603: high capacitance value MLCC, eg 1uF and up for X5R/X6*/X7*, and 1nF and up for C0G.
Recommended special series:
High Q MLCC and tight tolerance MLCC, for better performance in high frequency circuits.
