Anything about ceramic capacitors, i.e. particular capacitors whose dielectric is a ceramic compound.

Since some ceramic compounds can be realized with an extremely high dielectric constant (>>1000), ceramic capacitors can have tiny dimensions (say, a few mm) and still have high capacitance (up to about 100 μF).
