These stacked multilayer ceramic capacitors provide high capacitance solutions at ultra high temperature ratings for down hole and similar extreme environment applications. The multilayer ceramic dielectric also delivers lower ESR and DC leakage current ratings, better capacitance stability over frequency and substantially higher current ratings than comparable wet tantalum devices.
