V5, V6 - Reliability
Christos’ utility shows that 16 out of the 18 0603-sized X5R 10uF/6.3V capacitors operate at 6.0V. See the attached spreadsheet.
These should be changed by higher-rated voltage ones to increase the reliability as they are not overrated according to the usual guidelines.
The 0603 X5R 6.3V rated capacitors should be replaced with C0G 16V rated capacitors if available in the same package. C0G capacitors are more expensive, but show a good capacitance stability over temperature and when operating close to voltage rating value.
