AI Overview
100% accelerated steady-state aging (or screening) for tantalum capacitors is a rigorous burn-in process where 100% of the parts are tested under elevated voltage and temperature, typically 85°C, to ensure high reliability by inducing early failures. This process is standard for high-reliability components, such as polymer or MnO2 tantalum capacitors, used in medical and military applications.
Key Aspects of 100% Accelerated Aging Tantalum Capacitors:
- Purpose: To eliminate early life failures (infant mortality) and stabilize the electrical parameters of the capacitor.
- Conditions: Often combined with 100% surge current testing and 100% voltage/temperature aging.
- Series Examples:
- KEMET T495/T530/T545 Series: High-reliability MnO2 and polymer tantalum capacitors feature this screening to ensure low ESR and high ripple current capability.
- Polymer Technology: Conductive polymer cathode materials offer a "benign failure mode" during high-stress testing compared to standard MnO2.
- Applications: Ideal for demanding, high-reliability circuits in aerospace, military, and medical devices.
These, KEMET Series for instance, are commonly used because they are resistant to changes in environmental conditions, according to the Considerations In Using Tantalum SMD Capacitors vs Ceramics article.

What is the problem with tantalum capacitors?
The failure of tantalum capacitors has often been linked to thermal and electrical overstress, as well as impurity-induced degradation of the Taâ‚‚Oâ‚… dielectric. Historically, leakage current (DCL) and accelerated life testing were the primary methods used for reliability assessment.Sep 25, 2025
