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 AMC3302. 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 AMC3302.
