wet tantalum capacitor as bypass caps in guitar amps

In the applications, we often encounter tantalum capacitor explosion problems, especially in switching power supplies, LED power supplies and other industries. Known with many advantages, tantalum capacitors have been widely used by many customers. There are three basic types of tantalum capacitors, manganese dioxide (MnO2), conductive tantalum polymer and wet tantalum capacitors. It is the cathode systems of tantalum to make the difference between tantalum capacitors. Where, A is the total effective area of the capacitor plate, ε is the electric permittivity of the medium and d is the distance between the two plates. Tantalum capacitors, regardless of their types, have a very similar anode construction that consists of highly pure solid tantalum powders that are sintered at high temperature to transform granulate tantalum islands into a porous structure with very large surface area for higher capacitance as shown by the following equation:

Sometimes, concerns about the supply of metal tantalum arise because it’s still largely available from conflict areas, which may raise ethical concerns about its use in product designs. Tantalum capacitors generally don’t have the problem of being dry-out or dielectric degradation that often occurs if the capacitors are stored discharged for long time. They do have some disadvantages, such as relatively low capacitance and low voltage ratings, but those are still sufficient for low voltage and low power applications.

They are more expensive than aluminum electrolytic capacitors but offer the unparalleled advantages, such as compact sizes, durable quality, and stable parameters. Tantalum capacitors are high-performance electrolytic devices.
