If you measure a ceramic capacitor, and the measured value is much lower than what you think it should be, the following might be the cause. Class 2 Ceramic Capacitors have a known downside called "DC Bias", which causes the capacitance to "derate" (be less). Class 1 ceramics, such as C0G/NP0, don''t have this problem.

How to test a capacitor: 5 ways with and without a multimeter
1. Expose the capacitor. Here, too, the first thing to do is to completely remove the capacitor to be checked from the circuit. All contacts to the circuit must be removed and the two poles of the capacitor made freely accessible.
5 Ways to Test a Capacitor
For a 25V capacitor, you could use a voltage of 9 volts, while for a 600V capacitor, you should use a voltage of at least 400 volts. Let the capacitor charge for a few seconds. Be sure to connect the positive (red) lead from the voltage source to the positive (longer) capacitor terminal and the negative (black) lead to the negative (shorter ...

Do Capacitors Get Hot?
As these components work, it is natural to wonder if they generate heat. The answer is yes, capacitors can get hot during operation, particularly when subjected to high currents, high frequencies, or excessive voltage stress. ... Leakage current refers to the small amount of current that flows through a capacitor even when it is fully charged ...
Physically Large vs Small Capacitors
So, if both capacitors (small and large) have the same capacitance then one will (more than likely) work up to a larger voltage. A capacitor that is polarized (e.g. electrolytic dielectric) can be physically smaller compared to a capacitor with a better (lower loss) dielectric and this is also a significant trade-off.
