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.

KEMET Webinars

Calculating the operational life of capacitors seems like an easy task, but care must be taken when calculating their lifetime. How life is calculated depends on the operating conditions and the device type.

In this live webinar, Jekaterina Stael von Holstein, Field Application Engineer at KEMET, presents the methodologies for calculating life...
