Capacitors must provide adequate effective capacitance under the applicable DC bias conditions they

experience in the application. Multilayer ceramic capacitors (MLCC) typically exhibit only a fraction of their

nominal capacitance under real-world conditions and this factor must be taken into consideration when selecting

these capacitors. This problem is especially acute in low-profile capacitors, in which the dielectric field strength is

higher than in taller components. Reputable capacitor manufacturers provide capacitance versus DC bias curves

that greatly simplify component selection.

Table 9-1 lists components suitable for use with the AMC3301-Q1. This list is not exhaustive. Other components

may exist that are equally suitable (or better), however these listed components have been validated during the

development of the AMC3301-Q1.
