Class II ceramic dielectrics: types, performance and applications

source: Capacitor Faks blog 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, […]

A user’s guide to snubber capacitors

source: Capacitor Faks blog Large voltage spikes are common in power circuits, especially during switching. Switching devices are exposed to large spikes during turn-off, and voltage suppression circuits are required to protect them. Circuits for protecting FETs, IGBTs and other switching devices from large voltage spikes produced during switching operations are commonly referred to as […]
