WET tantalum capacitors are known for their significantly higher energy density, reaching up to 1000 J/dm³ compared to the mere 12 J/dm³ of solid tantalum capacitors. They also have the advantage of higher voltage ratings, supporting up to 150 V, and can operate at much higher temperatures, up to 200°C.
On the other hand, solid tantalum capacitors offer benefits such as miniaturization, high long-term stability, and very low equivalent series resistance (ESR), making them ideal for applications requiring compact and reliable components.
