Class II dielectrics are made of ferroelectric materials. The most commonly used materials are alkaline earth titanates. Most Class II dielectrics are based on barium titanate (BaTiO3). These dielectrics exhibit less stability but higher volumetric efficiency than Class I types, and are very commonly used in electronic circuits for coupling, decoupling, bypass and frequency discrimination applications.
