Question

Which of the following is a component of a solid electrolyte tantalum capacitor, constructed similarly to the wet electrolyte version?

Option 1: Tantalum pellets
Option 2: Dry graphite coating
Option 3: Manganese dioxide powder
Option 4: Metal can sealing

Answer 1

Manganese dioxide powder is the component of a solid electrolyte tantalum capacitor that is similar to the wet electrolyte version, used as the solid electrolyte.

Step-by-step explanation:

The component of a solid electrolyte tantalum capacitor that is constructed similarly to the wet electrolyte version is manganese dioxide powder. This material is used in solid tantalum capacitors as the electrolyte, which interfaces with the tantalum oxide layer on a tantalum pellet that acts as the dielectric. This construction is somewhat analogous to the role played by MnO2 in the wet version, which also involves a paste electrolyte containing manganese dioxide in wet cells. So, Option 3: Manganese dioxide powder is the correct choice.
