14/07/2020  Wet tantalum capacitors have several advantages over solid tantalum, aluminum electrolytic, and ceramic capacitors. As with all other capacitors, these advantages lead to a very specific “sweet spot” or focused area of applications where the wet tantalum capacitor is the best and preferred choice. Wet tantalums require little derating and offer higher voltages (75 V, 100 V, and 125

HIGH PERFORMANCE WET TANTALUM CAPACITORS FOR

The original wet tantalum capacitors, developed by Mallory and Sprague, were non-hermetic or elastomer sealed designs provided in axial leaded or through-hole silver cases. The designs incorporated a sintered tantalum anode or pellet with a cathode which was plated or deposited upon the internal case wall. In almost all designs, the electrolyte is a 55 % sulfuric acid solution. The case must ...

Wet tantalum capacitors (the coun-terelectrode being a liquid) allow higher working voltages, up to a few hundred volts. In film and ceramic CAPs, thin layers of dielectric and electrode materials are stacked alternately, with alternating electrodes displaced to avoid contact between the opposing terminals. Figure 2 shows the typical construction of a ceramic capacitor. A few tens to hundreds ...

Are tantalum capacitors safe for use in new designs ...

"When used properly" tantalum capacitors are highly reliable. They have the advantage of high capacitance per volume and good decoupling characteristics due to relatively low internal resistance and low inductance compared to traditional alternatives such as aluminum wet electrolytic capacitors. The 'catch' is in the qualifier "when used properly".
