A ceramic capacitor is encapsulated with two leads that emanate from the bottom then form a disc. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. In ceramic capacitors, a relatively high capacitance is achievable in a small physical size because of its high dielectric constant.
Capacitors (originally called electrical condensers) are analog electrical components that can collect and store electrical energy. As a direct current flows into a capacitor, it charges with energy and releases an alternating current flow back into the circuit.
