Extended Life Test of Solid Electrolyte Tantalum Capacitors

摘要

Capacitance, dissipation factor and dc leakage of solid electrolyte tantalum capacitors were measured at intervals throughout a 26,000-hour life test. Seventy-five percent of ten capacitors survived with no degradation in properties and no indication of impending wearout. All failures were associated with a measurement period, leading to the inference that discharging and recharging operations may be a failure hazard. (Author)
