These charts depict the results of an endurance test where 6.3 Vdc was applied to a capacitor at 105°C. The capacitors were both rated for 6.3 Vdc, with one being a conductive polymer capacitor and the other an aluminum electrolytic capacitor. The upper chart shows the capacitance change, while the lower chart shows the ESR change. For aluminum electrolytic capacitors, the capacitance decreased and ESR increased with time. In contrast, the conductive polymer’s capacitance and ESR remained flat and showed a stable performance over its rated endurance of 2000 hours. This is due to their highly heat resistant electrolyte.
