Vishay Sprague Solid-Electrolyte TANTALEX™ Capacitors for High Frequency Power Supplies PERFORMANCE CHARACTERISTICS Operating Temperature: -55 °C to +125 °C (above 85 °C, voltage derating is required) Capacitance Tolerance: at 1 kHz, +25 °C ± 20 %, ± 10 % standard. ± 5 % available as special Dissipation Factor: at 1 kHz, +25 °C. Dissipation factor, as determined from the expression 2fCR, shall not exceed the values listed in the standard ratings tables DC Leakage Current (DCL Max.): at +25 °C: leakage current shall not exceed the values listed in the Standard Ratings table at +85 °C: leakage current shall not exceed 10 times the values listed in the Standard Ratings table at +125 °C: leakage shall not exceed 15 times the values listed in the standard ratings tables Life Test: capacitors shall withstand rated DC voltage applied at +85 °C for 2000 h or derated DC voltage applied at +125 °C for 1000 h Following the life test: 1. DCL shall not exceed 125 % of the initial requirements 2. Dissipation factor shall meet the initial requirement 3.
