2.4.1
In recent years, large value, low-voltage, surface
mount ceramic capacitors have become very cost
effective in sizes up to a few tens of microfarad. The
low-ESR, small physical size and other properties
make ceramic capacitors very attractive in many types
of applications.
Ceramic capacitors are suitable for use with the
V
However, some care is needed in selecting the capac-
itor to ensure that it maintains sufficient capacitance
over the intended operating range of the application.
Typical low-cost, 10 F ceramic capacitors are avail-
able in X5R, X7R and Y5V dielectric ratings (other
types are also available, but are less common). The
initial tolerance specifications for these types of capac-
itors are often specified as ±10% to ±20% (X5R and
X7R) or -20%/+80% (Y5V). However, the effective
capacitance that these capacitors provide in an appli-
cation circuit will also vary based on additional factors,
such as the applied DC bias voltage and the tempera-
ture. The total in-circuit tolerance is, therefore, much
wider than the initial tolerance specification.
The X5R and X7R capacitors typically exhibit satisfac-
tory temperature stability (for example, ±15%, over a
wide temperature range, but consult the manufac-
turer's data sheets for exact specifications). However,
Y5V capacitors typically have extreme temperature tol-
erance specifications of +22%/-82%. Due to the
extreme temperature tolerance, a 10 F nominal rated
Y5V type capacitor may not deliver enough total capac-
itance to meet minimum V
stability
Therefore, Y5V capacitors are not recommended for
use with the Vddcore regulator if the application must
operate over a wide temperature range.

In addition to temperature tolerance, the effective
capacitance of large value ceramic capacitors can vary
substantially, based on the amount of DC voltage
applied to the capacitor. This effect can be very signifi-
cant, but is often overlooked or is not always
documented.
