What are the dielectric materials of capacitors

Understanding Capacitor Types and Characteristics | DigiKey

Due to the high dielectric constant of these materials, the Class 2 ceramic capacitors offer a higher capacitance per unit volume but have lower accuracy and stability than Class 1 capacitors. They are used for bypass and coupling applications where the absolute value of capacitance is not critical.
