1. Why are tantalum capacitors so expensive?
Tantalum ore resources are scarce and the mining cost is high.
The manufacturing process is complex and the yield is relatively low.
It has excellent electrical characteristics, making it indispensable in high-end applications. -
2. What is the expected life of tantalum capacitors?
Under normal circumstances, it can range from thousands of hours to tens of thousands of hours, depending on the working conditions and manufacturer specifications.
-
3. Will tantalum capacitors deteriorate?
Yes, tantalum capacitors may gradually lose some of their performance when stored for a long time or in adverse environments.
For example, long-term exposure to high temperature and humidity may cause the electrolyte to evaporate or chemically change. -
4. What causes tantalum capacitors to burn out?
Common causes include applying a voltage exceeding the maximum allowable value, excessive current, high ambient temperature, and manufacturing defects.
