Vishay / Sprague Wet Tantalum Capacitors feature a broad capacitance range of 10μF to 22,000μF and working voltages of 6.3V DC to 125V DC at +85°C. These capacitors are available in high temperature (+200°C) or MIL-SPEC variants such as DLA 10004, DLA 15005, DLA 93026, and M39006/09/21 (CLR65 / CLR69).
WET TANTALUM AS A DC CAPACITOR One of the key methods of achieving higher capacitance values with tantalum capacitors is to increase the anode surface area by utilising finer higher CV tantalum powders - see Fig.7. Wet tantalum electrolytes, usually based on sulphuric acid, have limited ion movement and lower conductivity, thus the …
Advanced Wet Tantalum Capacitors: Design, Specifications and ...
Insertion of new types of commercial, high volumetric efficiency wet tantalum capacitors in space systems requires reassessment of the existing quality assurance approaches that have been developed for capacitors manufactured to MIL-PRF-39006 requirements. The specifics of wet electrolytic capacitors is that leakage currents flowing through electrolyte …
Thelife ofa wet tantalum unit is eventually limited byloss ofwater vapourleading to open-circuit. Results are presented for button style capacitors which suggest that this is in fact not a practical limitation. 1 INTRODUCTION In these days of advanced integrated circuitry, it is easy to overlook the intricacies of an apparently simple component ...

Wet tantalum capacitors have several advantages over solid tantalum, aluminum electrolytic, and ceramic capacitors. As with all other capacitors, these advantages …
The wet electrolytic tantalum capacitor was the first tantalum capacitor. It is in reality two electrochemical capacitors in series. It consists of a porous sintered tantalum anode, upon which has been grown a thin film of tantalum oxide (Ta2O5) which becomes the dielectric. The secondary capacitor plate is a combination of three materials.

tantalum capacitors is similar for different manufacturers, but varies significantly from lot to lot. A model explaining rectifying properties of Ta capacitors was suggested by Sikula, et al. at the 2001 Capacitor and Resistor Technology Symposium (CARTS) [4]. The model considered a tantalum capacitor as a metal-insulator-
Wet tantalum capacitors have poor capacitance retention at low temperatures making it necessary for the design engineer to "spec-in" more wet tantalum capacitors just to meet the minimum capacitance requirement at -55°C. ൔhe example shown in the picture and the table demonstrate how 1 MLSH capacitor can replace a parallel bank ...
