PIC24FJ256DA210 FAMILY
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 inter-
nal voltage regulator of this microcontroller. However,
some care is needed in selecting the capacitor to
ensure that it maintains sufficient capacitance over the
intended operating range of the application.
Typical low-cost, 10 µF 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 applica-
tion circuit will also vary based on additional factors, such
as the applied DC bias voltage and the temperature. The
total in-circuit tolerance is, therefore, much wider than the
initial tolerance specification.
The X5R and X7R capacitors typically exhibit satisfactory
temperature stability (ex: ±15% over a wide temperature
range, but consult the manufacturer's data sheets for
exact specifications). However, Y5V capacitors typically
have extreme temperature tolerance specifications of
+22%/-82%. Due to the extreme temperature tolerance,
a 10µF nominal rated Y5V type capacitor may not deliver
enough total capacitance to meet minimum internal
ments. Therefore, Y5V capacitors are not recommended
for use with the internal voltage regulator if the application
must operate over a wide temperature range.

CONSIDERATIONS FOR CERAMIC
CAPACITORS
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.
A typical DC bias voltage vs. capacitance graph for
16V, 10V and 6.3V rated capacitors is shown in
Figure
FIGURE 2-4
When selecting a ceramic capacitor to be used with the
internal voltage regulator, it is suggested to select a
high-voltage rating, so that the operating voltage is a
small percentage of the maximum rated capacitor volt-
age. For example, choose a ceramic capacitor rated at
16V for the 1.8V V
