Wet Tantalum Capacitors

Wet tantalum capacitors use a liquid electrolyte in their cathode hermetically sealed systems. These capacitors offer the highest energy density among the classical capacitor technologies. The liquid electrolyte provides a continuous self-healing action for the dielectric, leading to low leakage currents, high reliability and a higher range of applicable operating voltages. Due to the resistance …

Tantalum Electrolytic Capacitors

Tantalum electrolytic capacitors are known for its high capacitance in small dimenstions (high energy and power density), reliability and stability of its parameters. Traditionally, tantalums’ advantages over aluminum electrolytics have been found in terms of capacitance per volume, parameter stability over temperature, and longevity; tantalums in general do not suffer from dry-out problems or issues …
