High CV BME C0G

C0G multilayer ceramic capacitors (MLCC) are a ‘workhorse’ of the capacitor industry. C0G MLCCs are selected for high temperature stability, low dissipation factor (DF) applications where capacitance aging cannot be tolerated. In recent years, C0G MLCCs have been favored increasingly over film capacitors as higher volumetric efficiency state-of-the-art C0G MLCCs are becoming available. This paper discusses C0G MLCC recently introduced at KEMET. These BME C0G MLCCs utilize base metal electrode (BME) technology, combined with lead-free dielectric and termination systems. The resulting C0G MLCC systems exhibit relatively high volumetric efficiency combined with a high level of capacitance stability with respect to temperature. Additionally, these systems exhibit exceptionally robust highly accelerated life test (HALT) performance. Small device footprints (as low as 0402) are also available with these dielectric systems. These high capacitance per unit volume (CV) BME C0G MLCC products are suitable as film replacements for numerous applications, enabling the designer to select a capacitor that is environmentally green, as well as robust with respect to surface mount processes that require lead-free solder.
