Wet Tantalum Capacitors with Hermetic Seal
FEATURES
• Very High Capacitance • 150 to 4700µF • 6 to 15VDC • - 55°C to + 85°C
APPLICATION NOTES
Vishay STA represents a major breakthrough in Wet Tantalum capacitor technology. Its unique cathode system, also used in the ST, provides the highest capacitance per unit volume available. The STA combines the inherent reliability of wet tantalum with the capacitance stability of solid tantalum, and there are no circuit impedance restrictions. The range is exceptionally well suited for low voltage filtering and energy storage applications. a) No continuous reverse voltage permissible. b) Transient reverse voltage surges are acceptable under the following conditions: The peak reverse voltage does not exceed 1.5 volts and the peak current times the duration of the reverse transient does not exceed 0.05 ampere seconds. In addition, the repetition frequency of the reverse voltage surge is less than 10Hz. c) The peak of the applied AC ripple and the applied DC voltage must not exceed the DC voltage rating of the capacitor. d) Ripple current ratings by part number at 85 ºC and 40kHz are included in the table. Ripple current correction factors for other temperatures and frequencies are given on the next page.
